However, as long as the Flower Temple is not under repair, it will generally be open, and you can also see exquisite butter sculptures, but it is not as brightly lit and shocking as the Lantern Festival. But it also avoids the pain of rubbing shoulders and heels.
As for the Lantern Festival accommodation, forget it. First, I can't book a good room (that's quite nervous). Second, even if there is a room, the sanitary conditions are not good. You can go back to Xining to stay that night, within 30 minutes by car.
