Back and Forth (2010)

The only cable car over Yangtze River in China is in Chongqing. Zheng Liang, 23, and Ms. Shi, 55 are both working there. They are good friends. Like a mother and a son, they chat, joke and share pieces of life everyday together. In less than three months, when spring comes, Ms. Shi will retire after her 30 years working here. Zheng Liang will have to continue the back and forth life over Yangtze River by himself.
