There is a printing factory and a printing factory in Li Huaping, Zengchan Road, Hebei District.
There are several printing houses on this side of Zhangxingzhuang Street. I remember the largest one is called Yin Bo Printing Factory, which is just behind Yantuo Bridge. Turn right at the subway station (towards Tiedong Road).
