There is a little explanation needed here: the ethnic Jingpo minority reside in the Yun-Nan province of Southwestern part of China is the same people as those lived in Burma, the Kachin. Their language and the primitive lifestyle are completely different than those from urban centers but their way was perfect to live in the remote mountains.
Most Chinese kids are the single child of the family, and they are selfish, spoiled and egotistic, as the result of being pampered by their parents and grandparents, and this movie did an excellent on criticizing this and documenting how the kid had grown up suddenly during his stay with the Kachin people. Most Chinese parents and grandparents should watch this movie so that their kids, as well as the adults themselves could grew up without experiencing the harsh lifestyles like our little protagonist in this movie.
