Yunnan tour guides have the best quality. According to the relevant public information, Yunnan Provincial Tourism Bureau has carried out strict management and training for tour guides, requiring tour guides to have good professional ethics, warm and thoughtful service attitude, solid professional knowledge and fluent eloquence. Therefore, when traveling in Yunnan, tourists can enjoy high-level tour guide services, and it is easier to obtain rich tourism information and cultural knowledge. Some tour guides in Sichuan lack professional knowledge and cultural accomplishment. It is impossible to accurately introduce the historical background and cultural connotation of scenic spots to tourists and popularize popular science knowledge. As a tourist hot spot, Guizhou is also facing great competition pressure for tour guides, and some tour guides may take improper measures to get more business, thus affecting their service quality.
