Jiarong Tibetan is one of four groups of Tibetan, who live in some districts of Ganzi and Aba. They have no writing, and they speak a dialect of Tibetan.
The style of Jiarong Tibetan house is special. The house is made of stones. A tower and a multi store building combine a house. Four horns on the roof represent the respect of god of mountains, stones, waters and winds. Three colors, white, red and black, painted on the wall mean pure, lucky and free from evils; another explanation is that three colors represent the respect of the god of heaven, the god of the earth, the god of underground. On a wall of a living room, there is a pattern of the sun and the moon.
All of these patterns come from local religion, Ben, the original religion of Tibetan. Nature worship is the spirit of Ben.
A tower and a multi store building combine a Jiarong Tibetan style house. There are two kinds of configuration. One is inseparable configuration. A tower and a multi store building can be built respectively. The other is dissociable configuration. A tower is the base of the house, so it should be built firstly, then the other part.
People believe that there are gods of houses. When an inseparable house is finished building, a lama is invited to pray for the god of the house. If the family is willing to abandon the house, a lama should be invited again. However, a lama is invited to the family twice when a dissociable house is done, for the tower and for the other part. If the house is abandoned, people can’t dismantle the tower, or the god of the tower will be angry. So people can find many abandoned towers, but hardly see an abandoned building.
One-tree ladder is used in Tibetan house of Danba. I think, it's easy to be made, and is suitable to be set in a narrow space of a tower. Most of them are safe. After I climbed up and down several times, I used to it. My guide said one day an American lady falled from it because she was overweight. But don't worry, she was ok, the ladder which she falled from was a short one.
