I traveled to Yunnan in mid-September this year and set out from Shenyang. What's the offer?

Nonsense upstairs, it's the peak season. As long as it is a round trip for more than six days and the lowest price is 3500, and the price is floating, don't believe it online. Find any regular local travel agency and ask them for a quotation, which is the most accurate.

I tell you from experience, don't look for anything too cheap. I can't find a fake one, but the service quality is poor. The guide will take you into the shop.
