Why did Suzhou recruit so many factories?

First of all, Suzhou has developed so fast only by foreign capital. Why did foreign capital come in? Start a factory, start a company. With more factories and companies, there will naturally be more people looking for objects.

Secondly, most factories are labor-intensive, and employees earn money mainly by working overtime. If there is less overtime in a certain period of time, employees naturally want to change their homes to work overtime, which is very mobile, and the factory has to constantly recruit people to supplement the lost employees.
