Due to the free visa and the relatively low price of flights (although not so low if one does not want to fly chinese carrier), I am thinking to go to China end of February - early March. I already had 2 trips there : 5 nights in Xi'an and 5 nights in Shanghai. Every trip I stayed into the city proper. I do not speak a word of Mandarin, I am OK taking public transport.
I was thinking to do something like this, what do you guys think:
Land in Shanghai
3 nights in Shanghai
Train to Hongzhou
3 nights in Hongzhou
Train to Nanjing
4 nights in Nanjing
train to Shanghai
2 nights in Shanghai
Depart back to Europe

Maybe stopping on the way back to Nanjing in Suzhou for 1 night but that start to be a lot of packing/unpacking.
Does that sound OK ? I already have been to Shanghai so the time there would be go on some water town in the outskirt I think + possibly do some museum I did not visited before + walk around as I really enjoyed the city my first visit.
Nanjing seems like a town relatively out the touristic path and a good opportunity to see modern china. I am a bit afraid of the level of English there though ?
I generally like history, temples, nice landscapes but I am a very urban person. So landscape are nice but it needs to be accessible by public transport. Hence Hongzhou who seems gorgeous.
