In murals of the Mogao Cave 285, the wooded mountains, animals and meditating monks can be seen as the relative independent scenes in the whoe paintings. According to Mahasamnipta stra,the author of this paper thinks that the wooded mountains, animals and meditating monks in Buddhist cottage reprsent the Trishasra-mah-sahasra-loka-dhtu, animals of the 12 two-hour periods practising srvaka and visiting Jambu-dvpa to do philanthrpic act and depart from evil, and Bud-dhist who have received sermon or are doing practice respectibely. The animals of the 12 two -hour periods and Twelve Symbolical are an inherent contents of Chinese cultrue. That an-imal and mauntain forest were taken as traditional subject matter in ancient Chinese pamtings is of long standing. In the process of a mixture of Buddhsm,Taoism and Confucianism of the Southem and Northern Dynasties, the subject matter and even form of Chinese paintings were used by Buddhist art to Buddhist doctrine: alternate teachings of the animals of the 12 two-hour periods.
