Where can I buy second-hand books in Tianjin?

Nankai Cultural Palace has long been demolished. Now it has moved to Anshan West Road, New Times Cultural Square (opposite Tianda North Gate, next to Xihu Village Station, one stop before Tianda Genius). There is a sign that says "Mimia Book Fair" (but it has been put aside, so it is difficult to find it without careful reading. Just look for the "New Age Cultural Square". What a big sign-)

There is also a Confucian temple in Guwen Street, but the books are really old, and the quantity is small. We have to go in the morning (there are many gadgets there now, so it is recommended to go on Saturday and Sunday).

There is also the "Ancient Books Bookstore" on Golden Street, which is quite small, but the reference value of the literature is relatively large and the price is a bit expensive. If you enter Golden Street from the entrance near Central Park, walk to the right for a while and you will see it. It says "Ancient Books Bookstore" in gold font. This store needs to be searched carefully to know. In an alley, although the name of the store can be seen on Golden Street, the real store can only be seen in the alley. If I remember correctly, there seems to be a copper pot selling Longkou in Hutongkou.
