The weather in Nanjing is March.

Yes, April is better. The temperature is not very warm in March, and the holiday in May is the peak season for tourism, and so is 10 month. Then, in April, spring blossoms.

I live in Nanjing. I used to work in Suzhou and Shanghai, so I have been to almost all the places you mentioned. It is ok to go to the ancient town of Tang Xi from Monday to Friday.

I went to Hangzhou in April and went to Hangzhou again on March 3 1. The willows and peach blossoms by the West Lake are in full bloom. If it is sunny, it is beautiful. Of course, I can go in autumn, because the lotus is blooming, which is also a kind of beauty!
