I have been studying where to play in summer these days, hehe! I have studied Jiuzhaigou, Lijiang River in Guilin, or Kunming in Yunnan. I think the scenery in these places is particularly good. Personally, I like places with mountains and water. The cost depends on how you play! I'm preparing for a self-help tour. If these places are economical, they can be done within 2000 by train and around 3000 by plane! Joining a group is not bad, and the price is not expensive, but the time is too fast. I prefer to have free time!
