Thanks for the invitation.
First of all, according to the current trend, there will still be a period of high temperature in Hangzhou in September. In this case, it is good to visit Qiandao Lake. I have also visited Qiandao Lake alone, and the conclusion is that hotel selection is very important, because the time can be controlled by one person, and there is no need to visit too many scenic spots. Just walk a few representative ones and choose a room with a panoramic view, which is perfect.
