The quietest place is not easy to find. Government-level libraries such as Shenzhen Library and Security Library are open to the whole people in crowded places, so there are many people inside, so it is difficult to find places on weekends.

Shenzhen Science and Technology Library is the quietest library in my opinion, with a good environment, relatively rich collections, beautiful venues and open to ordinary people. It's just that it's relatively difficult for you to find this library. In Nanshan and Shenzhen University Town, it is composed of graduate schools of Harbin Institute of Technology, Tsinghua and Peking University, all of which are branch schools. There is a main road in the campus that enters from the gate of Harbin Institute of Technology. Go along the road and you can see the gates of Tsinghua University and Peking University. The library is next to Peking University HSBC Business School!

"The world is magnificent and strange, and the extraordinary scenery often lies in danger. Where there is a will, there is a way." This sentence also applies today, haha

Good luck. I think this is the best and quietest library in Shenzhen. You'll know when you go.
