大家好，我是氓叔，一个讲真话不掺假的区块链从业者。
Hi, I'm Uncle Sun, a real-life block-linker.
上期视频里，我重点讲了区块链在打破阶级固化，变革生产关系方面的社会意义，发出来之后，虽然观（bian）看（ji）量（bu）不（gei）太（tui）大（jian），但还是收获了不少好评。尤其有个朋友说看完视频后很感动，区块链让他看到了未来走向社会公平的希望，这真的是让我非常欣慰。
In the last video, I focused on the social significance of block chains in breaking the rigidity of classes and changing productive relationships, and after it came out, I received a lot of good comments, even though I saw (bian) not (bu) (gei) (ji) (jian). It was really gratifying for me that a friend in particular was moved when he said that the strong (strong) chain showed him hope for future social justice .
于是这个用爱发电的第二个视频，今天它来了！
So this second video of power generation, it's coming today!
这期我们就一个主题，比特币！
We're on one theme, Bitcoin!
比特币这个主题，B 站现存的视频内容乏善可陈，当然我的意思不是全盘否定，B 站 UP 主还是有不少人才的。我的意思是大部分视频都只是偏重某一个侧面来讲，没有把这个贯穿了技术，金融，经济体系以及货币理论等诸多领域的大主题串起来，导致你看了之后，感觉明白了，但实际还是不明白。
The topic of Bitcoin, the video content of station B is not very good, of course, and I don't mean total negation, but the owner of station B has a lot of talent. I mean, most videos focus only on one side, not cutting across a wide range of subjects such as technology, finance, the economic system, and monetary theory, which leads you to see it, but it still doesn't.
不信的话，你可以看看能否回答下面这几个问题？
If you don't believe me, can you see if you can answer the next few questions?
比特币的价值是什么？比特币的经济模型是怎样的？比特币的信任是如何通过技术传递的？比特币是怎样保证不能账目造假的？比特币是不是货币呢？
What's the value of the bitcoin? What's the economic model of the bitcoin? How does the bitcoin trust pass through technology? How does the bitcoin guarantee that the accounts are not faked? Is the bitcoin the currency?
我就不继续往下问了，以上问题一个都回答不了的请扣 0，能够回答一半的请扣 1，全都知道答案的请扣 2。
I'm not going to ask any more questions, but I'm not going to be able to answer any of these questions, and I'm going to be able to answer half of them, and I'm going to be able to answer all of them.
我猜大部分人应该都是 0 或 1 的水平。
I guess most people should be at 0 or 1 level.
比特币是区块链的基础，这些问题搞不懂的话，贸然入场进行投资是有非常大的风险的。孙子曾曰（不读 ri），知己知彼，百战不殆。啥都不懂就敢拿着钱往里冲？庄家不割你割谁呢？
Bitcoin is the foundation of the chain of blocks, and if you don't understand these questions, there is a great risk of going into the field and investing. The grandson once said, "Don't read the ri."
建议不想搭乘天台直通车的朋友们赶紧点个关注，不然你哪天被邪魔外道骗上车，那可就什么都晚了。
It's suggested that friends who don't want to take a direct ride from the roof take a quick look, or you'll get into the car one day by the devil, and it'll be too late.
想给我三连的朋友请不用克制自己，尽管冲我来，不想给的朋友也不用着急，high 点都给你在后面埋好了，相信我，你肯定会想的。
You don't have to restrain yourself if you want to give me three company friends, even if you come to me, you don't have to give them to anyone who doesn't want to.
下面，我们正式开始。
Here we go.
时间回到 2008 年，次贷危机爆发，全球经济衰退。
Time went back to 2008, when the subprime crisis broke out, and the global recession.
次贷危机以美国房地产市场的崩溃为导火索，由于大批量贷款买房者没有能力偿还债务产生坏账，导致次级贷款机构破产。同时，在基于房贷的金融衍生品的杠杆推动下，进一步放大了房产市场对金融市场的冲击，最终导致了金融危机在全球蔓延。
The subprime mortgage crisis was triggered by the collapse of the real-estate market in the United States, which led to the bankruptcy of sub-lending institutions because of the inability of large numbers of loan buyers to pay their debts. At the same time, the impact of housing markets on financial markets was further magnified by leverage of mortgage-based financial derivatives, ultimately leading to a global financial crisis.
对次贷危机感兴趣的朋友，推荐看一下电影《大空头》，由于此处不是今天讨论的重点，我就不做展开了。
Friends interested in the subprime crisis are advised to look at the film " Big Empty ", which is not the focus of today's discussion, and I am not going to do it.
每个乱世里，英雄的身影都会闪现，有人选择挺身而出，揭竿而起，也有人不想走到前台，只想默默做贡献。
In every troubled world, heroes emerge, and some choose to stand up, raise their arms, and others do not want to go to the fore, simply to contribute in silence.
中本聪属于后者。
Nakamoto belongs to the latter.
次贷危机归根结底是由于在宽松的货币政策下，不合理的超发货币而埋下的祸根。既然这样，如果有一种货币限制发行总量，永远无法超发，是不是就不会有金融危机，也不会有货币贬值等一系列连锁问题了呢？
The subprime crisis is ultimately due to the scourge of unreasonable excess currency under loose monetary policy. So, if there is a currency that limits the volume of issuance, it can never exceed, there will be no financial crisis, and there will be no chain of problems like currency depreciation.
于是，精通密码学和编程的中本聪，一拍脑袋，说干就干，拿起键盘用 C++ 编码，实现了自己脑海里的构想。
So, the middle-breeder, who is proficient in cryptography and programming, takes a shot of the head, says dry, picks up the keyboard and uses the C++ code to achieve the idea of his own mind.
比特币就这样诞生了。
That's how Bitcoin was born.
比特币的设计非常具有革命性，技术实现上融合了密码学和 P2P 网络，并首创了UTXO 模型和 POW 共识机制等。听起来这些名词有点唬人，但你不用担心，今天我不讲密码学也不讲编程，我会把比特币降维到幼儿园辍学水平来讲，保证你能听明白。
Bitcoin's design is very revolutionary, technology has combined cryptology and P2P networks, and it's the first UTXO model and Pow consensus mechanism. It sounds a bit preposterous, but don't worry, I don't talk about cryptography or programming today, and I'm going to send bitcoin down to kindergarten levels to make sure you can hear it.
比特币的本质是一个去中心化的数据库，所有的设计都是围绕着让这个去中心化的数据库能够正常工作展开。
The essence of
什么叫去中心化数据库呢？去中心化数据库和中心化数据库相对应。
What do you mean, decentralised? Decentralized databases correspond to centralized databases.
当你打开支付宝，看见自己的账户余额有 100 元时，这个数据就是记在支付宝中心化数据库里的，支付宝拥有数据库的完全控制权，它可以决定谁能看谁不能看，决定谁有权限对数据库进行修改。
When you open the payment treasure and see the balance of your account at $100, the data is recorded in the centralised database of the payment treasure, which has full control of the database, which determines who can see who cannot see and who has the authority to modify the database.
而去中心化数据库，与此机制完全相反。去中心化数据库不归属于任何一方，所有人都可以查看其记录的数据，所有人也都有权限对其进行修改。
The decentralised database is not owned by either party, and everyone has access to the data they record, and everyone has the right to modify it.
聪明如你，一定发现数据库被这样一搞之后，就引入了很多问题。
As smart as you are, it must have been a lot of questions when the database got hit like this.
这数据库有什么价值，怎么通过它赚钱？
既然大家都有记账权限，那以谁为准？
如果有人故意记假账捣乱怎么办？
别着急，我们一个一个来。
Don't worry, we'll come one by one.
任何生意本质上都是以赚钱为目的，这个去中心化数据库的生意也一样，想要让这个系统运转起来，首先要解决的，就是如何让这个去中心化数据库的参与者赚到钱。
Any business is essentially about making money, and the same is true of the decentralized database business, which wants to make the system work, first of all, how to make money for the participants in the decentralized database.
面对这个问题，中本聪神来一笔，用了一招无中生有！没有价值就想办法创造价值！
In the face of this problem, the Chinese God of the Wise has done everything in his power to create value without value!
任何一个有价值的事物，都必须满足这 3 个要素：
Any valuable thing must satisfy these three elements:
1、具有稀缺性，不能无限产出。
2、具有使用价值，能满足特定的需求。
3、要可交易，能够流通。
中本聪拎着这三板斧，开辟出了数字货币的新天地。
Nakamoto carries these three axes, opening a new horizon for digital money.
首先，中本聪在写代码的时候限制了比特币的发行总量，全球有 78 亿人，但比特币一共就 2100 万枚，不够分自己想办法，多了没有了。
First, when writing the code, China has limited the total distribution of Bitcoin, with 7.8 billion people around the world, but that's 21 million pieces of bitcoins.
其次，比特币的这个去中心化数据库系统，可以让你以极低的成本持有资产，这一点稍微有点抽象，我还是来举例说明吧。
Secondly, this decentralised database system in Bitcoin allows you to hold assets at a very low cost, which is somewhat abstract, and I'd like to give you an example.
现实世界中，持有资产其实是有额外的成本消耗的，或是维护成本，或是转移成本。
In the real world, holding assets actually consumes additional costs, either maintenance costs or transfer costs.
例如你去年在北京买一套房，但今年你想换去深圳工作，要重新买一套，于是你需要支付各种中介费用，并花费大把时间把北京的卖掉并在深圳重新买，其间损失的钱就是转移成本。
For example, you bought a house in Beijing last year, but if you want to change jobs in Shenzhen this year, to buy a new one, you have to pay for all kinds of intermediaries and spend a lot of time selling Beijing and buying it again in Shenzhen, and the money lost is the transfer cost.
再比如你觉得通胀太严重了，想配置点黄金，金条买到手后，你发现如何保管是个问题，想了半天，最终决定去银行租个保险柜，于是你为了持有金条需要额外付银行租金，这就是维护成本。
For example, you think inflation is too high, you want some gold, you buy gold, you find it a problem how to keep it, you think about it for half a day, and you decide to rent a safe in the bank, so you have to pay extra bank rent to hold the gold, which is the maintenance cost.
最近的例子，就是美国原油期货跌成负油价，之所以发生，就是因为有钱买油，但没钱租储油设施，原油维护成本太高了，接盘就赔钱。
The most recent example is the fall in United States crude oil futures to negative oil prices, which occurs because there is money to buy oil, but there is no money to rent oil storage facilities, and the cost of maintaining crude oil is too high to pay.
相比之下，比特币的维护成本和转移成本都为 0，创下历史新低。比特币网络 7*24 在线，资产随时存入，随时取出，随时转账，只要手机连上网，大千世界任你闯！
By contrast, the maintenance and transfer costs of Bitcoin are zero, at an all-time low. The Bitcoin network 7*24 is online, assets are deposited at any time, assets are removed at any time, transfers are made at any time, as long as mobile phones are connected to the Internet, and thousands of worlds are open to you!
这么优质的资产属性，加上这么便捷的服务系统，让比特币在众多资产里脱颖而出，人们有了持有比特币的需求，也就等于比特币有了使用价值。
Such high-quality asset attributes, coupled with such a convenient service system, have allowed Bitcoin to emerge from a multitude of assets and have the need to hold bitcoin, which is worth using it.
最后，在可交易这一点上，比特币做得也很极致。
Finally, bitcoin was extremely good at the tradable point.
交易，其实本质上是一个事物的归属权的转移，想要交易，必须先解决归属权的问题。比特币的归属权是基于密钥体系实现的。
A transaction, in essence, is a transfer of the right to belong to a thing, and for a transaction to be made, the question of the right to belong must first be resolved. Bitcoin’s right to belong is based on a key system.
降维来看，比特币的账户体系，和互联网的账户名和密码很类似，我来类比一下，你就懂了。
Vi, the bitcoin account system is similar to the Internet account name and password, so let me compare it to you.
以支付宝为例，支付宝的账户名是你的收款地址，别人可以通过这个地址给你转账，而密码则是用来确认这个账户的归属，有了密码你就能登入账户，控制你的资产。
In the case of payment treasures, the name of the account for payment of the treasure is your collection address, through which others can transfer it to you, and the password is used to confirm the identity of the account and, with the password, you can enter the account and control your assets.
比特币的账户体系里，私钥等同于密码，地址等同于支付宝的账户名。区别在于支付宝的账户名和密码用户自主设置的，而比特币则是随机生成的。
In the Bitcoin account system, the private key is the same as a password and the address is the name of the account for the payment treasure. The difference is that the account name and password user for the payment of the treasure are set on their own, while the bitcoin is generated randomly.
创建比特币账户时，先会随机生成一个 256 位的二进制数字作为私钥，然后再通过一系列的密码学运算算出你的地址，两者一一对应，只要记住了私钥，你就可以完全控制你的比特币资产。
When a bitcoin account is created, a 256-bit binary number is generated randomly as a private key, and then your address is calculated by a series of cryptography exercises, which corresponds to one and the other, and you have complete control of your bitcoin assets by remembering the private key.
既然是随机生成的，那私钥有没有办法破解呢？破解算法很简单，只是你耗不起时间，即使当今全球的计算资源都供你使用，从宇宙诞生那天你就开始算，算到今天你都算不完。
If it's randomly generated, is there any way that the private key can crack it? The decryption algorithm is simple, it's just that you can't afford time, even if the global computing resources are available to you today, and you've been counting since the day the universe was born, and you've been counting them all to this day.
这大概是最朋克的账户体系了。
It's probably the most punk account system.
归属权解决完，配合起去中心化数据库这个天然大账本，来记录资产转移，交易问题，完美解决。
Ownership is settled in conjunction with the decentralised database, a natural large account book, to record asset transfers, transactional problems and perfect resolution.
综合这 3 个要素，满足了稀缺性，有使用价值和可交易后，比特币就被赋予了价值，比特币的系统从此活了起来。
Combining these three elements, satisfying the scarcity, and having a useful and tradable value, Bitcoins were given value, and the Bitcoins system survived.
中本聪这招无中生有打得行云流水，出神入化，颇有大侠风范。受此启发，后来有个金某，开始创作武侠小说，并以中本聪为人物原型，成功塑造了一位大侠形象，此人与东邪西毒南帝北丐齐名，人称中神通。
It was inspired by the impeccable nature of China, which led to the creation of a martial arts novel and the creation of the Chinese version, which successfully shaped the image of a warrior who was known as the North Korean King of North East and West, and was known as the God of God.
觉得中大侠这一招妙的，请把 “妙啊” 打在公屏上，如果发完弹幕还是觉得自己的崇敬之情无处释放，请三连投币了解一下。
If you think the Chinese master is smart, put the word "beautiful" on the public screen, and if you still feel that you have no place to release your respect, please pay a couple of coins.
书归正传，比特币我们继续讲。
Let's get back to the book, bitcoin.
给比特币赋予价值后，其实还只是解决了第一个问题，想要让比特币的体系运转起来，还有需要给所有参与者设计一套激励机制，把比特币的价值分享给参与者，让参与者赚到钱。
After giving value to Bitcoin, it was actually just the first problem to make the Bitcoin system work, and there was a need to devise a set of incentives for all participants to share the value of Bitcoin with the participants and make money for the participants.
中本聪为此设计了一套简单而巧妙的经济模型。
To that end, Nakamoto has designed a simple and smart set of economic models.
任何一个系统想要运转起来，两种角色必不可少，一种是服务的提供者，另一种是服务的使用者。在比特币模型里，服务的提供者是矿工，他们运行比特币代码，提供记账服务，服务的使用者就是持有比特币的普通用户。
In the Bitcoin model, the service provider is the miner who runs the bitcoin code and provides the bookkeeping service, and the user of the service is the ordinary user of the bitcoin.
矿工提供记账服务需要付出成本，所以他们需要赚钱，在比特币的模型里，矿工的收入来自两部分，一部分是系统发放的记账奖励，一部分是用户支付的转账手续费，这两部分都以比特币来结算。
In the Bitcoin model, miners earn two parts of their income, a part of the system's billing incentive and a part of the transfer fees paid by users, both of which are settled in bitcoin.
矿工挖矿时，比特币系统会陆续将 2100 万枚比特币作为记账奖励发给矿工，矿工获得了奖励，系统也同时完成了比特币的价值释放。作为用户，想获得比特币，需要线下从矿工手里去买，矿工卖出比特币后，可以获得现实收益，用户拿到比特币后，也就成为了比特币网络的用户，扩大了比特币的价值共识。
When miners dig, the Bitcoin system gives 21 million bitcoins to miners as an incentive for bookkeeping, the miners get the reward, and the system also completes the value release of bitcoins. As users, they need to get bitcoins, buy them off the wire, sell bitcoins, get real benefits, and when the users get bitcoins, they become users of the Bitcoin network, broadening the Bitcoin’s value consensus.
另外，为了增加矿工和用户的参与动力，比特币系统设计了收益递减的挖矿机制，越早参与越可以低成本获得比特币，享受更丰厚的增值红利。
In addition, in order to increase the motivation of miners and users, the Bitcoin system has designed a reduced-benefit mining mechanism that allows for earlier participation to obtain bitcoin at a lower cost and enjoy greater value-added dividends.
按照现在额挖矿速度，比特币收益每四年减半，假设减半前，挖一天可以获得 2 个，减半后，就只能获得 1 个了。此时比特币的新增供给减半，但新增需求不变，需求大于供给，比特币的价格也就自然而然的上涨了。
At this rate, bitcoin yields are reduced by half every four years, assuming two by one day before they are halved, and only one by one. At that time, bitcoin’s new supply is halved, but demand remains constant, demand is greater than supply, and the price of bitcoins rises naturally.
比特币的减半机制，是引发过去几次大牛市的根本诱因。
The halving of Bitcoin is a fundamental incentive for the past few major cattle markets.
这一套经济模型设计完后，比特币网络就具备了逐步发展壮大的动力，但如果想要健康成长，还需要解决一个关键问题：
With the design of this set of economic models, the Bitcoin network has gained momentum over time, but a key issue needs to be addressed if it is to grow healthy:
有人搞破坏怎么办？
What if someone destroys it?
这就要讲到比特币的共识机制 POW，共识机制是确保矿工所记账目真实有效的根本保障。
比特币的矿工是没有数量限制的，但只有你抢到了记账权限，并完成记账，才能获得比特币奖励。所以问题来了，矿工那么多，但每次产生一个区块（约10分钟）才需要记一次账，这个宝贵的记账权限我要如何公平公正的分给矿工呢？
Bitcoin miners don't have quantitative limits, but you can get a bitcoin reward only if you take the bookkeeping rights and finish the bookkeeping. So the problem is, there are so many miners, but it takes one account at a time (about 10 minutes) to produce a block. How do I share this valuable bookkeeping rights with the miners in a fair and equitable way?
面对这个问题，中本聪的解决方案也很朋克，矿工爱谁谁我不管，我就给你个密码学的问题，谁第一个找到答案，谁就获得记账权。
Faced with this problem, the smart solution in
这个密码学的问题没有捷径可走，每个人都只能按照给定的计算方式去穷举计算，你的设备计算性能越好，越有可能先算出答案。为了争夺记账权，矿工需要购买专业的矿机并为其交大量电费，投入成本高昂，只有通过诚实记账获得比特币奖励，才能收回成本。
There are no shortcuts to this cryptology problem, and everyone can only count according to a given calculation, and the better your computing performance, the more likely it is that you will be able to figure out the answer first. In order to compete for rights, miners need to buy specialized machines and pay large amounts of electricity for them, and the cost will be recovered only by obtaining an honest accounting reward in bitcoin.
但在这里，中本聪故意留了个 bug。
But here, Nakamoto deliberately left a bug.
既然谁算的快谁获得记账权，那如果我掌握的算力达到了 51%，我比其他人加起来算的都快，那我不就可以想怎么记账就怎么记账了？
If I have 51% of the power, I'm faster than everyone else combined, then I can't write as much as I want.
对，但这个攻击理论上可行，实操则是亏本的生意。
Yes, but the attack was theoretically feasible, and it was a bad business.
大家都是利益驱动的，你在发动攻击前，先要想想自己能获得什么。倘若你有富可敌国的家底，你倾家荡产买矿机交电费，终于算力达到了 51%，然后发动攻击，并且成功了，此时会发生什么呢？
We are all profit-driven. Before you launch an attack, think about what you can get. What happens if you have a rich enemy home, and you pay 51% of the money to buy a miner, and then launch an attack and succeed?
首当其冲的是比特币的信任体系崩塌，既然有人能操纵账本记假账，比特币也就不可信了，你通过攻击获得的全部比特币，马上变得一文不值。同时，你为了攻击买的矿机，也再也卖不出去，所有的货，全部砸手里。
The first hit was the collapse of the Bitcoin trust system, and now that someone can manipulate the books, the bitcoin is untrustworthy, and the entire bitcoin you got through the attack becomes worthless. At the same time, you can't sell any more to attack the mine that you bought, and all the goods are in your hands.
在比特币网络里，只有老老实实的诚实记账，才能赚到钱。
In the Bitcoin network, only honest accounting can make money.
比特币有了价值，有了经济模型，有了反作弊的共识机制，这套系统就可以自己汲取营养，放肆生长了，从此海阔凭鱼跃，天高任鸟飞。
Bitcoin has value, an economic model, and a consensus mechanism against cheating, so that the system can feed itself, grow and grow, and the sea can leap from the sea to the sky.
若干年之后，比特币会发展成什么样子呢？会成为全球统一货币吗？
What happens to Bitcoin after a few years? Will it become a global currency?
这个问题的答案见仁见智，我的答案是不会。
The answer to this question is ingenious, and my answer is no.
一个好的货币体系，总体是适度通胀的，在尽量保证货币价值稳定的同时，让货币的供应量和经济发展总体成正比。
is a good monetary system that is generally moderate in inflation and that, while maximizing the stability of monetary values, allows for a positive overall ratio between the supply of money and economic development .
经济的发展是螺旋上升的，在爆发初期，货币可以适量超发以保证经济发展有足够的弹药支撑，出现泡沫后，货币应该允许出现通胀，回落到真实价值，金融泡沫很难避免，但只要适度，其实不会阻碍经济发展。
Economic development was spiralling, and in the early stages of the outbreak, the currency could outpace enough to ensure that economic development was supported by enough ammunition. After the bubble, the currency should allow inflation to fall back to real value, and the financial bubble would be difficult to avoid, but it would not be an obstacle to economic development as long as it was moderate.
但比特币的体系是通缩的，通缩的体系不能超发，因此也就限制了经济发展的初始动力。同时通缩的货币会随着经济发展增值，既然拿着就能坐享增值利息，借款人便没有了借款动力，由此便会导致市场产生流动性枯竭，企业无处贷款发展业务。企业借不到钱，经济就不会大踏步的发展。
But the system of ‘strong’ bitcoin is a deflationary system
虽然成不了全球统一货币，但并不妨碍比特币是一个革命性的数字资产。
, while not a globally unified currency, does not prevent Bitcoin from being a revolutionary digital asset .
在全球数字化的浪潮中，越来越多的东西开始线上化，数字化，随着互联网越来越发达，人类正以肉眼可见的速度，建造一个崭新的数字世界。
In the wave of global digitization, more and more things are getting online and digital, and as the Internet becomes more and more developed, humankind is building a brand new digital world at a rate that is visible to the naked eye.
这里有人类沉淀数千年的文化精华，这里有丰富多彩的娱乐方式，这里还有联动全球的社交网络，此时，这里正需要一种属于数字时代的新资产。
At a time when there are thousands of years of cultural sank, where there are rich ways of entertaining and where there are social networks that connect the globe, a new asset of the digital age is needed.
比特币弥补了这个缺憾。
Bitcoin made up for this.
在这个没有权威，透明公开的网络里，信任开始生根发芽，越来越多的人相信比特币，持有比特币，使用比特币。在过去的十几年里，比特币在各种看衰中越挫越勇，它已从极客圈子的乌托邦走出，变成了得到法律认可的合法财产。
In this unauthorised, transparent and open network, trust is beginning to take root, and more and more people believe in bitcoin, holding bitcoin, and using bitcoin. In the last decade or so, bitcoin has been foiled in all kinds of decline, and it has emerged from the utopia of the utopian circle and has become legally recognized as a legitimate property.
虽然比特币还未成为真正的主流，也未摆脱贴子自己身上的高风险标签，但不可否认的是，以它为代表的去中心化的信任体系，正在引领资产数字化的新浪潮。
Although Bitcoin has not yet become a real mainstream and has not escaped the high-risk label on its own, it is undeniable that the decentralized trust system represented by 波诡云谲，风云变幻，虽然比特币的未来发展之路，依然会道阻且艰，多方势力的打压也有可能让比特币命悬一线。 While the path to the future of Bitcoin continues to be blocked and difficult, the pressure of multiple forces threatens to put Bitcoin's life on the line. 但是我依然坚信比特币不会归零，这不是因为技术崇拜，更不是因为精神信仰。 But I remain convinced that bitcoin will not go zero, not because of technical worship, not because of spirituality. 而是我坚信在未来的世界里，我们需要这股，信任的力量。 It is my conviction that we need this power of trust in the future world. 感谢各位的三连和关注，我们下期见！ Thank you all for your attention and attention. I'll see you next time!
