To put it bluntly, Wenzhou was too poor to eat enough more than 20 years ago, so the country turned a blind eye to this barbarian land. At that time, Wenzhou people were forced to die at home without going out to make money.
But at that time, many parts of the country were poor, especially Anhui and Wenzhou. Most poor people in these places go begging for food. Think about how many beggars can become billionaires.
Wenzhou people choose to go out to polish shoes, cotton, be plasterers, carpenters, farm on the beach, and be tailors. Many of these people later became billionaires.
