You can turn to foreigner street after dinner. (Foreigners Street doesn't accept tickets, which is similar to Chengdu Happy Valley)
Return from foreigner street, take a bus at the gate, get off at Longmen Haoyue Station, walk to Banpo, cross the river cableway to Yuzhong District opposite, and the fare is 5 yuan/person. Get off the ropeway and walk to Chaotianmen Wharf. You can buy a boat ticket to see the night view of the two rivers at 7: 50, 58 yuan/person. After disembarking, there should be a wandering singer singing on the dock.
Book a room online before you go. For example, the Cocoa Cottage in ciqikou ancient town is not bad. After catching an all-night train to Shapingba, I took a taxi to Ciqikou. When you get up early the next morning, you can try the "cat face" diagonally opposite the Ciqikou archway.
The next day's route reference is Ciqikou-Zhazidong-Baijiating-Ciqikou-Jie Fangbei-Chongqing North Station. (Shapingba takes subway 1 line, and it takes about 30 minutes to get to Jie Fangbei. When you come back, you can transfer to Lianglukou Station of Metro 1 Line and take Light Rail Line 3 to Chongqing North Station).
