I've seen this Japanese movie on the 48th Melbourne International Film Festival. It is such one of the great films I have seen. I think the novel should be a good starting point of this film. It is the story about Japanese business, development, money and high technology to a far far away village in Yunnan, China. Certainly, some people argue that pure nature would be destroy and they can do anything to against the project of development. The researcher team difficultly get there. When they finally are in the village, people there are very nice. The villagers believe that their ancestor could fly. What is the truth that the team discover? Go to watch this movie. You are going to know then.
Anyway, I wouldn't love this film if the end wasn't like this. You need to see this perfect end by yourself. There is no word to explain. As well, you need to go to listen to the theme song. It makes me mad about the sadness of the character.
