How about the tickets for Huicheng Yunnan Tourism? Is it reliable?

Go ahead. In order to save money, so don't expect too much, after all, saving money is for consumption, and you should buy it. Or spend a tour fee of 2-3 thousand yuan, and the cost market price of Yunnan tour is at least 2000+. Personally, I will choose the former, because if the same itinerary is arranged, it would be too bad to have a lot of tour fees.
