The Longchang temple on Baohua mountain is famous for its strict discipline and enjoys the reputation of "the first famous mountain of the law school", but the source of Buddhism lies in the Zen method created by Baozhi monk of the Liang Dynasty. During the Chongzhen period of the Ming Dynasty, master samadhi, the abbot of Longchang temple, changed the Buddhist temple into a law temple, advocated law and paid attention to preaching precepts. Longchang Temple gradually became the center of Chinese law. However, Zen did not die out in Longchang temple. Instead, it was passed on by eminent monks from generation to generation. As a result, Emperor Kangxi of the Qing Dynasty renamed Longchang Temple "Huiju Temple". Emperor Yongzheng, with the Zen opportunity of "not mind but Buddha", asked the then host Wenhai to "observe the machine and understand the mind" to invent the original mind. Emperor Qianlong went to Jiangnan for several times to climb mountains and ask Zen, feeling that "Zen is round and precept". Countless literati left poems about Zen. It can be seen that Longchang temple is not a single important town of law in history. While strictly preaching precepts, it also secretly preaches Zen. For various reasons, this history is not well known to modern people. Investigating this period of history and revealing the Zen method of Longchang temple, which has been buried in the long river of history, can enrich the academic research on Zen since the Ming and Qing Dynasties.
