You can take bus No.535 at the north and south gate of Southwest University to the Three Gorges Square in Shapingba, and take bus No.808 at the bus stop opposite Xinhua Map Bookstore in the Three Gorges Square to Cikou.

Take the light rail after returning to Shapingba, because it is a little far from Jie Fangbei or Chaotianmen. Take the subway 1 line and get off at Little Cross, or change to Light Rail Line 2 at Daping and get off at Linjiangmen, which is Jie Fangbei. That's what happened when we walked to Hongya Cave in Jie Fangbei. Ask for advice. Chaotianmen is not far. The three places are next to each other.
