The Yungang Caves in Datong Shanxi Prov?ince which were built during the Northern Wei Dynasty are one of the most valuable cultural treasures in the world. They always attract a good many tourists. They can remind us of China's long history and make us greatly amazed at the splendid culture in ancient China. In addition by visiting the Yungang Caves we can broaden our horizon and enrich our knowledge. Unfortunately the ancient Buddha statues in the caves have been badly damaged by a large amount of industrial dust in recent years. Many governments now make great efforts to protect cultural relics. In brief there is no time to delay to protect the Yungang Caves.  There is no doubt that measures should be taken to protect the caves and statues. The factories which produce heavy pollution should be moved away and glass walls should be built around the statues. If enough attention is paid the caves will be preserved for a longer time.
