Can Yunnan tourism apply for a patent?

No, patent refers to the formulation of patent law in order to protect the legitimate rights and interests of patentees, encourage inventions, promote the application of inventions, improve innovation ability, and promote scientific and technological progress and economic and social development. You didn't invent Yunnan tourism, it is an established language formed by people for a long time. You are not qualified to apply for a patent, so you can't apply for a patent. You can consider applying for a trademark, but the Yunnan Provincial Administration for Industry and Commerce will never let you pass. If passed, it will violate the country's unfair competition law.
