Yangzhou is a good city with few industries, spacious roads and few people. It is more leisure, and Heyuan, Geyuan and Slender West Lake are also good. The only drawback is that the train is inconvenient and you can only rely on long-distance buses.
Zhenjiang, personally feel that tourism is not good. Just a few famous temples. If you are not devout Buddhists, don't go to this city.
Changzhou is famous for its dinosaur park, but every city has an amusement park. I think there will be a large amusement park in Qingdao, so the city can not go.
Wuxi, the tourism in Wuxi has been good in recent years. Wuxi film and television base, Lingshan and Zhutouzhu are all very good, but Zhutouzhu suggests going in April when there are cherry blossoms. In addition, many free parks have been built along the Taihu Lake in Wuxi, and the scenery is very good. Suggest staying.
Nanjing, because Nanjing is the city to go back and the last stop. Nanjing has many scenic spots and cemeteries. You can visit the Sun Yat-sen Mausoleum and the Ming Tombs.
The following is my suggested route for reference only:
1 On that day, I went to Yangzhou from Qingdao and stayed in Yangzhou at night.
The next morning, I tasted steamed stuffed buns in Fuchun Building, Yangzhou, and then visited the scenic spots in Yangzhou. I can choose 1 or two scenic spots and live in Yangzhou at night.
On the third day, it takes about 3 to 4 hours to get to Wuxi by car in the morning. You can go to Wuxi at noon, so you can visit lingshan scenic spot and stay in Wuxi at night.
On the fourth day, I visited Wuxi Film and Television Base. It is suggested to visit San'guo City and Water Margin. In the afternoon, you can choose 1 free scenic spots, or go to the city center to have a look and taste snacks, then take the high-speed train to Nanjing, about 2 hours' journey, and stay in Nanjing at night.
On the fifth day, I visited Sun Yat-sen Mausoleum, Ming Tombs and other scenic spots, visited Confucius Temple, and flew back to Qingdao in the evening.
This trip will be easier without two cities, otherwise it will be very tiring to go to those cities. If you want to know more about any scenic spots, you can consult me again. I know these cities well.
