If you are in Shanghai, Suzhou might be a good experience for a day trip. Specially recommended to go in spring, as there are lots of flowers in some of the venues.
Suzhou is an ancient water city, west of Shanghai. I booked a half day tour on Chirstmas Day and I was the only person on the tour so I got a private tour guide and a driver. I loved the old narrow water ways and architecture of this old water city.
It's my house with my living. I like some of flowers round my staying for a long time. Then there is fresh air making human healthy. It's all.
About 100km west of Shanghai, Suzhou is home to some of the very finest examples of what this country does best: traditional garden architecture. There are a number of truly spectacular private gardens that can be visited here, but nothing beats the 'Humble Administrators Garden', which is absolutely outstanding. The areas of the Old City, with their canals and traditional houses, are pleasantly atmospheric, and there are a number of great places to stay here if you want to make it more than a daytrip from Shanghai or Hangzhou.
