Recently, a number of precious cultural relics, such as stone letters, gold-plated silver coffins and Jintanzi, have been found in the underground palace of xinglong tower, Yanzhou City, our province. This great discovery is very rare in China, and it is of great value to the study of history and culture, Buddhist history, painting art and production technology.

After identification, stone letters, gold-plated silver coffins and sarira gold bottles are national first-class cultural relics, while sarira tablets and glass bottles are national third-class cultural relics.

The stone letter is the outermost sarcophagus for burying the Buddha relic. Figures and patterns are carved around the stone characters and on the top cover. The pattern shows the image of dharma protector and Buddha disciple, with the purpose of protecting the Buddhist relics in Shihan.

The gold-plated silver coffin is made of silver with a gold-plated surface, which is 47 cm long, 20 cm wide and 20 cm high. The surface carving patterns are vivid and rich, showing the nirvana of Sakyamuni from left to right. The Buddha lay on his side slightly, with his chin in one hand and his eyes closed, and all his disciples were sad. Other aspects show Buddha, disciple, bodhisattva and other Buddha gods.
