One day, you can go to Chongqing Jiefangbei, which is a famous business district. It is said that it is also one of the places where beauties appear most frequently in the world. Have snacks at Bayi Road at noon. Then you can go shopping in Chaotianmen Square and take a ride on the river-crossing cableway (which first appeared in "Crazy Stone", and it seems that this does not exist in other places).
The next day, you can go to Bai Gongguan and Zhazi Cave to commemorate the revolutionary martyrs and feel the spirit of Hongyan; then go to Chongqing’s People’s Square, which includes Chongqing’s People’s Auditorium. A building imitating the Temple of Heaven; in the evening you can go to Nanbin Road to eat and enjoy the night view. When night falls, find a small bar by the river to drink wine and enjoy the river breeze, which is a unique experience.
On the third day, you can visit Ciqikou, a thousand-year-old ancient town, where you can eat many unique snacks.
The above are some places you can visit in Chongqing. In the remaining four days, you can selectively visit some surrounding places. For example, Dazu Rock Carvings (although I don’t think it is very interesting, but it is a world cultural heritage after all), Little Three Gorges, Fengdu Ghost Town, etc. There are quite a lot of small attractions around Chongqing. I'm not very familiar with this aspect. You can choose to find a travel agency to help you arrange your travel around the area.
