When you go, you have to make an appointment in advance, a total of 3 floors. There are very few people, and there is only one person when I go. The aunt at the front desk followed me. When I went to a hall, she helped me turn on the lights in advance. After reading it, she turned off the lights, 😂️😂️😂️😂️, and then went to the next one. It should be to save electricity, very good, but waiting at the entrance of the hall, I always feel that someone is urging, and it will come out in less than 40 minutes. Like the patience of the aunt
