If you want to take the elderly to eat Beijing snacks, you can go to Jiumen snacks in Houhai or Huguo Temple snacks in Xisi (head office). Famous snacks in Beijing include braised pork, fried belly, fried liver (authentic Tianxingju in Xianyukou Hutong in front, or Qingfeng steamed stuffed bun, but Qingfeng steamed stuffed bun can only be said to be very general), almond tea, noodles tea and so on. Inby can eat bean juice, but only Beijing people make it delicious and sell it outside (in Zhajiang noodles)
Old people can bring some snacks from Daoxiang Village when they go home (pay attention to buy them in Beijing Sanhe brand Daoxiang Village store in residential areas, usually Suzhou Daoxiang Village on the streets such as railway station, Wangfujing and Qianmen), garlic sausage and sauce elbow in Daoxiang Village, sauce elbow in Tianfu, roast mutton (sauce beef) in Yueshengzhai, pickles in Liubiju or Tianyuan (the old shop is close to Tianxingju), and tea in Zhang Yiyuan or Wuyutai (front door).
The Forbidden City (Tiananmen Square, Chairman Mao Memorial Hall) is a scenic spot not to be missed. By the way, visit Qianmen or Wangfujing to let them feel the business atmosphere in Beijing. Note: It is best to book tickets online in the Forbidden City and rent an interpreter for them after entering.
The Summer Palace and Yuanmingyuan are famous royal gardens, which should be visited. If you are not very old, I suggest you visit the Great Wall.
If the elderly are well educated, I suggest visiting the National Museum, the Capital Museum, the National Library and the China Art Museum.
It's best to drive or take a taxi to take the old man from Xidan to Guo Mao at night to see the lights on Chang 'an Avenue.
It's enough for 3-5 days. Old people must combine work and rest and not be too tired. Note: Tickets for the park for the elderly over 60 are half price, and those over 65 are free. Please bring your ID card.
