Tsinghua really has nothing to go if it is not an academic exchange. It is nothing more than a pile of modern western-style buildings and two ancient quadrangles in China. If you want to see the West Building, the Red Building in Peking University is not far from Tiananmen Square. If you want to see the ancient buildings in China, you can go to Jingshan in Beihai if there are many people in the Forbidden City. The most important thing about a school is its humanistic atmosphere, which you can't see at a glance.
Nanluoguxiang is the most ignorant place. I don't see any features of old Beijing. Those so-called cultural and creative industries are still very expensive. A TB cigar clip sells for 5 yuan, and no one will buy it if it sells for 50 yuan there. Looking at the hutongs in old Beijing, I suggest going to the north shore of Houhai (not Shichahai in a bunch of bars, but the former residence of Soong Ching Ling). Seeing old Beijingers, I suggest going to Beihai Park, Temple of Heaven and Ritan.

Route? Flag raising must be "every1"(1,1,2 1, 3 1). Under normal circumstances, the guard of honor will not come out. And it's best to wait until the end of 18DA, which you should understand. When watching the flag-raising ceremony, be sure to arrive when there is no bus. Basically, you can take a taxi to Wang Hongbin or Nanchang Street, and then walk to the sidewalk opposite Tiananmen Square. Forget it. You have to go in. Bring your own bread for breakfast or something.
After watching the flag-raising, there will be a time difference in opening the park. Use this time to stroll from Nanchang Street to Beichang Street and then to Jingshan South Street on the back of the Forbidden City, then go to Jingshan Park, enter from the south gate, exit from the west gate, enter Beihai Park from the east gate via Tushanmen Street, exit from the north gate after the tour, and walk east along Ping 'an Street to reach the intersection of Di 'anmen. Di 'anmen snack in the northwest corner of the crossroads is an authentic Beijing halal restaurant. Noodles tea, mutton offal soup, fried bumps, fried belly and bean juice are all important. Save some room for this meal, go north, go to the drum tower, and go a little further east. Yao Ji Fried Liver is a typical Beijing Hanmin snack bar, which mainly tastes fried liver and braised pork. Off-topic, fried liver is actually to put a few pieces of liver in the fat intestine to improve the taste, so don't ask why it's all intestines without liver when buying. After eating, I ran along the inclined street of the tobacco pouch and wandered along the north coast until I could stay in Deshengmennei Street. There will be nine kinds of snacks on the road, which can be ignored because what you just ate is much more affordable than this.
