Is Tianjin Port Authority only allowed to enter Tanggu?

As long as it is a Tianjin hukou [120XXX], you can enter the port authority. Now you must have good social relations to enter the port authority, otherwise it will be difficult to enter.

Knowing the cadres at or above the division level of the port authority should be no problem to get in.

The salary of the port authority is average, mainly because the benefits and bonuses are relatively rich!
