Kgrou, grain warehouse in Tuonuo Village
A kgrou is a grain warehouse used by the Tuonuo people, a minority group in southern China. From a distance, it looks like a mushroom. Its body is built away from the ground, and the reason is that the ventilation is good so that the stored grain does not rot, and to prevent mice from eating it. Between the pillar and the body, wooden boards, jars, stones, cast iron pots, etc. are inserted to prevent mice from climbing up. Kgrous are built in groups outside the village. The reason is to avoid being threatened with survival by burning all the grain in case of a house fire. Small items may be stolen in Tuonuo Village, but large items are not stolen. Therefore, even if the kgrou is outside the house, there is no need to worry about thieves.
