Please plan the route! Depart from Zhengzhou and travel to Nanjing, Yangzhou, Wuxi, Suzhou, and Shanghai in seven days! Suzhou can be replaced by Hangzhou...

In Nanjing, you can go to Xuanwu Lake Park, Confucius Temple and Sun Yat-sen Mausoleum in two days, and you can also go shopping in Xinjiekou without tickets. You can go to Slender West Lake and Dongguan Street in Yangzhou in one day. I don’t know if the tickets are expensive. There is nothing interesting in Wuxi, it doesn’t matter whether you go or not. You can spend 2 days in Suzhou to go to Suzhou Park where there is a Ferris Wheel Park and other places, and then go to places like Guanqian Street on Pingjiang Road. In Shanghai, it is recommended to go to Happy Valley for a tour, the ticket price is about 200. If you take buses and subways in every city, the transportation fee of around 300 is basically enough to travel to these cities. When it comes to accommodation, it depends on your own choice. There are expensive ones and cheap ones
