I have moved and have study room service, but it closes at 5: 30 in the afternoon. I don't know the address, so I know it's not far from the copper building, because I looked for it for a long time last time. I didn't write down the address because I closed at night. Hebei district library has self-study service, go! Every day 1.5 yuan, monthly ticket to 25 yuan, closed at night 19:30. The environment is ok.
