What month is the cheapest and most suitable for traveling with a group in Yunnan?

Let's go in September. The rainy season has just ended, and there is still a little tail, but it has not yet reached the Eleventh Golden Week, which is very cost-effective.

This year 1 1 month, there are tens of thousands of Lijiang tourists sleeping on the streets. I heard that there are small tents everywhere.

March is also fine.

Other months are peak seasons, with too many people and expensive prices.
