Two days and one night in Beijing on weekends, seeking travel strategies.

I'm not sure about your taste. Two days and one night is a little nervous. There are many places worth going, so you can't take care of them all. Two girls, I think I will like places like Houhai and Nanluoguxiang. You can go now. You can go to both places at night. Go to some regular scenic spots during the day. Tiananmen Square, Forbidden City, Wangfujing and Xidan are all on the same line, so you can go together. If you like factory art, I suggest you go to 798. If you want to go to Badaling Great Wall, plan your trip one day in advance, about one day. Come back at least at three or four in the afternoon. If you go to Beijing North Railway Station (Xizhimen Railway Station) and buy a bullet train to the Great Wall, you will arrive at 1 hour. You should buy a return ticket when you get off the bus, so as not to go back. Just arrange your own pace according to the return time after buying the ticket.
