What is painting a pie?
When Masayoshi Son started his business, he hired a few workers at the dock and enthusiastically told them, "We are going to become the greatest company in the world." Upon hearing this, the workers all ran away.
When Ma Yun started his business and talked about the grand vision of the internet and e-commerce, people regarded him as a fraud.
Success is a dream. Failure is painting a pie.
The term 'painting a pie' is a mockery by a group of inferior and lowly people towards brave losers.
The upper class must paint a pie, and it should be a big pie. If that pie succeeds, then it has succeeded; if luck is not on their side, at most they will be scolded by the inferior people for 'painting a pie,' which is not a loss.
