Beautifully filmed, with fantastic acting (the two children are particularly amazing), this movie portrays, with a simple but effective script, a very moving story about Tibeto-Burman ethnic Lisu people in remote mountainous areas of Fugong County, in the west of Yunnan province bordering Myanmar. That people in the countryside need to use zip-lines in order to cross wild Nu River. There is no feasible alternative way for some children to go to school, or for physicians who shall attend the sick in some remote areas. Is solidarity enough when the State ignores poor people in those far away places?
