After reading your comments, we set out in Lianzhou early in the morning. We drove about half an hour to the scenic spots, which opened at 8:30. We arrived at about 9:15, and many people had already bought tickets, but it was not as exaggerated as National Day. It took about 10 minutes to change tickets successfully. Inside the scenic spot, there is no need to queue, they are all following you. We are arranged to take the boat first and then walk; in some cases, we first walk and then take the boat, diverting some people. It seems that there are many ways to go up stairs by boat, and then to go out of the cave and then to cross a mountain before returning to the entrance. Generally speaking, the air in the scenic area is fresh, and taking children out for a walk is also a good choice.
