One of the four famous passes is Jiangshan City by bus first, and then by bus 201 at Chengbei Square to Baoan Township. There are buses at 7:40 and 9:40 a.m., with 10 Yuan Road fare, about an hour and a half, and 60 tickets, including Dai Li's former residence and Xianxia Pass. The scenery of the ancient road is very beautiful, there are not many people, it seems very quiet, like a paradise, a path with mountains on both sides, divided into four passes, the first one is a little far, but two, three and four are very close. At the beginning of Baoan Township and at the end of Longjing Village, there are buses going back to Jiangshan on the way to Longjing Village.
