I'm going to Kunshan on business on May 2nd, and I want to visit Suzhou, Hangzhou, Shanghai and Nanjing. Where can I go first? How is the weather?

If you go to Kunshan first, then you can go directly to Suzhou by bus. It takes an hour, and the high-speed train takes nearly ten minutes. If you are in Suzhou, go to Xiapingjiang Road, Humble Administrator's Garden (Suzhou Museum is next to Humble Administrator's Garden, so you can visit it for free) and Huqiu, and go to Shantang Street to see the night scene at night. Then you can go to Nanjing, where the high-speed train costs about 100 yuan an hour, and the train takes nearly two hours to 70 yuan, but the frequency is less. In Nanjing, there are Sun Yat-sen Mausoleum, Ming Mausoleum and Meihua Mountain. In the evening, you can visit the Confucius Temple, the Presidential Palace and Xinjiekou. After that, you can take the high-speed train directly to Shanghai for one and a half hours 140 yuan. In Shanghai, the most famous are the Bund, the Oriental Pearl and Nanjing Road. Finally went directly to Hangzhou. If you go to Hangzhou, you will definitely go to the West Lake (the West Lake is not enough for one day), and then Lingyin Temple. If you still like the ancient town, I suggest you go to Wuzhen, Jiaxing, Zhejiang, which is beautiful and elegant and can stay for one night. Suzhou also has ancient towns, and Tongli is also good. Zhouzhuang doesn't recommend it because it is too commercial.

As for clothes, it's about 25 degrees in Suzhou now, and the surrounding temperature should be similar. You should look at the weather forecast and be prepared, but the temperature difference between morning and evening is still quite large, so you should take a thin coat.
