I'm from Fuzhou, and I want to take my parents to travel to Beijing. Are there any good and affordable tour groups?

You don't need to join a tour group, but 6000 for four people is still a little small: the toll train sleeper Z 60426 * 2 * 4 = 3,408 yuan. Accommodation: Stay at least 4 nights. The first stay is very expensive. Consider it 200 nights. 200*2*4= 1600 yuan. Tickets: I wonder how old your parents are. If you have an old-age card, don't forget to bring it. Urban subway+bus (including the Great Wall and 13 Mausoleum) can basically be solved. Not much to say, there is too much information on the internet.
