The library on the other side of the administrative center square has the most complete collection. It is the largest and highest-grade one in Dongguan. There is also a branch next to Guancheng Science Museum (that is, the North Gate of People's Park). There is one on Dongcheng Canal Road. I forgot the name of the library. It doesn't matter. I have been to all three books. I hope I can help you. Happy new year.
