Why is business good in chaozhou people? Where is their shrewdness reflected?

As a Chaoshan person, I have some feelings about this. It is true that Chaoshan people are good at doing business. After all, it is influenced by the traditional business culture of Chaoshan for thousands of years, and the hipsters who work hard outside are also very moral and loyal. I deeply agree with this. However, it does not rule out that there are some black sheep. Their business methods are not aboveboard, giving outsiders an illusion that we Chaoshan people are like this. This is called "a mouse excrement spoils a pot of porridge". The landlord doesn't have to care too much. Chaoshan people's excellent business tradition is still there, so it will not be greatly affected.
