I plan to travel to Nanjing, Suzhou, Hangzhou and Shanghai this afternoon. I wonder what the weather is like.

Note: 1, heatstroke prevention and cooling, umbrella, it is best to bring some heatstroke prevention medicine. Especially at the World Expo, there are often long queues. Off-topic: I can't figure out why those people are willing to wait in line for hours to see a museum. Not to mention fatigue and high temperature, time in China is so cheap. Even if there are aliens inside, I won't wait in line for hours. 2, security, in fact, the Yangtze River Delta region is one of the best areas of domestic security, but when you go out, you must always pay attention to yourself. 3. Arrange the time reasonably. These places suggest that Hangzhou and Nanjing can arrange more time, because there are many things to see and play. Although Shanghai is relatively large, except for the World Expo, there are no scenic spots and so on. You can only visit the Chenghuang Temple and Lujiazui (Bund). Suzhou landscape architecture is also good, but after all, the city is very small.
