We have a very bad experience with the Many Trees Hostel in Jinghong. We made a booking there a few days ago. When we arrived, they said they didn't receive the booking. And they said it the fault of the YHA China website. If you put your hostel on a site for booking, people expect you to look at that site, but that was below these people. They said all the rooms were taken now, but five minutes later a Chinese couple came in, and they gave them a room. Apparently, there is a double standard. When we asked the reception to help us find something else, they wanted to send us to a hostel with only dorms, which only had space for one night, and they were very rude. When we asked for hotels in the neighbourhood they said there were none and were very rude again.
This is a very unfriendly, bad hostel. And they call themselves many trees, but there are no trees, it's a shared courtyard in an ugly building.
