Tourism in Hangzhou, Suzhou and Shanghai

I have a week to travel to Hangzhou, Suzhou and Shanghai. I want to save time and have fun. I suggest you go back by plane or by train. It is the first time to fly to Shanghai, about 2 hours, and play in Shanghai first. You can visit the Oriental Pearl, the China Pavilion of the World Expo, the night view of Nanjing Road and the Bund, the Yuyuan Garden for sightseeing and shopping, and the old Shanghai for one or two nights. Then go to Suzhou, visit four famous gardens, Hanshan Temple and Tiger Hill Park, and stay for two days and one night. Finally, I went to Hangzhou and visited the West Lake and Song Cheng. If you have enough time, you can also increase the Qiandao Lake scenic spot. Finally, return to Xi by plane or train from Hangzhou. Another suggestion: have fun and save trouble. Before departure, you can ask the local travel agency to help you plan your itinerary and scenic spots, and ask them to book hotels, round-trip buses and air tickets on your behalf, and contact the tour guides in the above three places for reception. This is more convenient.
