"Good fortune," "Eight diagrams," "Snake twining round nine eggs" are symbols for safe travel often seen on vehicles, horse saddle and gear, boats and ships. They are also used for residential houses and buildings. These symbols are on each side of the entrance to the tent in Tibet or yurt in Mongolia. The in-house symbol of Tibetan dwelling, a constitution of mountains, the moon and the sun, is
of the same nature and function. It was first seen on house-ware carvings from Dawenkou culture in Shandong Province.
