This is a miracle work of one-man construction - a box. Zhang Suying, a woman of more than 60 years old, when she wandered from home, it is not known here, a person built a house like a "castle" on the idle land next to the abandoned brick kiln, which amazed everyone. The owner of the surrounding farm said that the house, which is seven or eight meters high, had been built by hand for four or five years. She retrieves her useful stones and waste building materials from a garbage pit two kilometers away, and increases her "castle" by even half a centimeter every day, even on snowy days... The film uses the technique of flashback, starting from the search for people after being demolished, escaping from rescue and finally leaving, in Zhang Suying's words: to the other side, to the high place.
