Can a person join a tour group?

can a person join a tour group? This actually has two meanings: 1. I travel to Dunhuang alone and see Dunhuang attractions: Dunhuang Mogao Grottoes, Mingsha Mountain, Crescent Spring, Yumenguan, Yangguan and Yadan landform. Can I join a tour group? And hotels and guesthouses are generally standard rooms. How to arrange accommodation? 2. There is only one person in the tour group. Will you go out every day as promised? A: One person can join the tour group, so why not travel alone! Of course you can. Hotels are basically standard rooms and single rooms, so when you stay in hotels, if you are alone, you can stay in a single room. This situation is explained in the relevant tourist routes.
