Recommend everyone to come here, few people, good experience. The appearance is quite depressed, but there is really no hole in the sky, there is a biggest hole very shocking. There are few people, 10 people will assign an explanation, no other tourists on the way, and there are dark river cruises to sit. There are too many people in Yinziyan, it is very hot and humid, crowded, and there is no special impression all the way. Funny and fun, worth recommending, good scenery, good experience,
