What preparations should be made for tourism in the Yangtze River Delta?

First, determine the first stop and the last stop. Such cities generally choose provincial capital cities with more convenient transportation, and at the same time, safety, catering, etc. are guaranteed to be better. For example, based on the principle of "from far to near", you can design Hangzhou as the first stop, spend a few days in Hangzhou, and then travel back one stop at a time, first going to Putuo Island, Shaoxing, and then Yandang Mountain, Qiandao Lake, then Wuzhen, to Shanghai. After visiting Shanghai for a few days, I will go to Suzhou, Wuxi and Yangzhou. Finally, we went to Nanjing and returned after spending a few days in Nanjing. Of course, you can also go in the opposite direction, first to Nanjing and finally to Hangzhou.
