There is a Xinhua Bookstore opposite Dongli Shopping Mall.
However, there are limited categories of ripe products.
I suggest you take bus No.830 from China Resources Development Zone to Tianjin Book Building.
The books there are complete.
And it's very convenient to go to Dongli Development Zone.
You can go and see.
Get off at 830 Dayingmen Station.
Only a few steps away.
