Where are many factories in Taian?

Tai 'an City (Taishan District and Daiyue District are rare) certainly does not exist. The land price is too high for ordinary factories to enter. The Ciyao Economic Development Zone in Tai 'an is a provincial-level development zone, and now it is developing rapidly, and there are more people recruiting, that is, wages have just started and will rise in the future. My answer is for reference only and I hope it will help you.
