After visiting the concentration camp in Shangrao a few years ago, Dad thought about visiting the dregs cave in Chongqing. This time, he decided to come to Chongqing for a visit. After checking the map, he felt that it was inconvenient to go to the dregs cave, so he wanted to put it in the last place. On that day, we went to the dregs cave directly by taxi after visiting the Expo Garden. It was 50 yuan. There was a traffic jam on the way up the mountain (probably on Sunday). The driver suggested that we walk up the mountain. Fortunately, we didn't go far. Along the way, there are a lot of pullers wearing red waistcoats. One of them is to take a bus to pick up all the scenic spots on the mountain. In fact, only 20 yuan is required for the regular sightseeing bus in the scenic area. We didn't take a bus because we were not interested in other scenic spots on the mountain. We just wanted to go to the dregs cave to see where Jiang Jie was imprisoned. There are so many tourists in the dregs cave. Every place has to queue up for a visit. After shopping, I wanted to take a taxi and found that there was still a traffic jam on the uphill road. So I went down to Baigong parking lot. There was a bus going to the magnetizer port subway station for 10 yuan each. But there were too many tourists and the queue was too exaggerated. We called the netizen car. Haha, it only cost 8 yuan to the magnetizer port.
