It may be because the time to go was wrong, and it happened to rain at night, so I looked at Taihu Lake on the top of Lushan. It was foggy and I couldn't see it clearly. The sky was also very dark. Because of the spring, the trees are not lush, so the whole Lushan does not seem to have the feeling of a 5a scenic spot, and the 4a level is almost the same.
