Sanlitun, Beijing, a good place for shopping. There is a Yaxiu Clothing City next to Sanlitun, where there are many clothes (if you are not demanding, you can find your favorite items here, but the price here is relatively high, and the bargaining power depends on you). Soho Sanlitun has a good chance to see Hong Kong stars filming.
Qianmen Street, you can go in the evening. There are many snacks in Beijing.
Gongwangfu, you must go and see it. Look at the house in Xiao Shenyang, which was a treasure trove of geomantic omen. Look at Xiao Shenyang's paintings and see how rich he really is. This is the location of Princess Zhu Huan, which swept the country ten years ago.
The Summer Palace is also a must. Look at the 17-hole bridge, the residence of Empress Dowager Cixi, the first electric light in China, and Kunming Lake, where the soldiers were trained.
