Spring Festival travel rush is an annual "liquidity squeeze" in China. A large number of cows and horses, like Nian beasts, return home with firecrackers ringing and then leave. Usually, people are treated as production factors and dispersed in various cities to run models. During the Spring Festival, all cases will be subject to mandatory liquidation and will be returned to the public account in a unified manner. The system does not crash, indicating that its scheduling capability is indeed the world's top. But the problem is: people are not assets, they have emotions. High speed rail is essentially a 'high-frequency matching system'. China has spent trillions of dollars to create the world's strongest matchmaking engine, The result of the match was not a transaction, but rather: external short videos+goose and duck killing voice chat+full carriage conference calls. Do you think this is a 'quality issue'? No, this is typical: the hardware has been upgraded, but the user has not. Just like you put a knockoff coin, Forcefully listed on top exchanges, No matter how powerful the matchmaking system is, it cannot stop a bunch of people from smashing the market. Many people start sitting in business seats and say, 'It's quiet over there.'. Simply put, when public order cannot be guaranteed by rules, it can only rely on price stratification. This logic is the same everywhere: Stocks: VIP channel Exchange: Market maker priority Reality: Business Class, First Class You're not buying services, You are escaping from the crowd. The most ironic point is: China is one of the few countries in the world that can handle the level of traffic during the Spring Festival travel rush, But it is also a minority that requires noise cancelling headphones to survive in top tier infrastructure. The essence of a business seat: Use money to buy yourself an environment where 'others don't talk'. When a society needs to filter quietness by price, the essence is that the rules have already expired.
