What chapter is it about Chu Huan and Nan Shan Che?

Chapter 12 of Inside and Outside Mountains and Rivers: Interaction between Chu Huan and Nanshan. In this chapter, Chu Huan came to a county town, met Nanshan and was taken to the deep mountains. There, Nanshan cured Chu Huan and invited him to teach children in the mountains. Chu Huan found these children strong and brave, and the mountain was also eccentric. The clan headed by Nanshan is nominally a mountain keeper. For most of the year, they can't get out of the river and go to the world where ordinary people live.
