I don't remember how many times I admired Chairman Mao. Every time I was in a very exciting mood. This time, the security check in Tian'anmen Square is very strict. The ID card, security check and physical examination have been carried out several times. It cost 50 yuan to deposit the bag. It opens from 8 to 12 a.m. every day. Don't go out of the square before you finish swimming in it, or you'll have to go through the security check again. It is convenient to take the bus from Qianmen East Station to Beijing West Station.
