I want to take my parents to Suzhou, Hangzhou and Shanghai for a few days. When is the right time to go?

Well, I admire your filial piety. Let's take a three-day or four-day tour: I suggest not to find a tour group: tour groups spend too much money. It is more convenient to drive or take the train at the beginning of the route. I wonder if you are from Shandong. If you suggest going to Penglai Xiandao first, you must go: take your parents by boat. Buy something delicious. Then go to Taihu Lake to eat hairy crabs. Then the next day, Kunshan Forest Park was very big. Or go directly to Shanghai. Parents visit the zoo, because parents rarely see real animals: then take the subway 10 line: Shanghai Chenghuang Temple, and the pedestrian street: Yuyuan Garden. Watch the Oriental Pearl at night. Remember to buy some gifts for your parents, such as a jade watch. Since you are traveling, you should bring some gifts back and remind your parents of your filial piety when you see them. Then go to Hangzhou West for a walk: climb Leifeng Tower, visit the broken bridge and see the snow. Take bus No.7 to Beifeng. If you haven't had enough fun, go to Qiandao Lake. If you want to escape, go to the Potala Palace in Dali, Yunnan. Remember, since you choose to travel, don't be afraid to spend money to bring charging treasure and protective equipment. It is rainy in spring now. I suggest you choose to go when it doesn't rain for several days in a row. Watch the weather forecast.
