hen the Koryŏ(高麗) dynasty, which had been invaded from Mongghol, entered the Yuan(元) intervention period, the Koryŏ temples connected with the Yuan imperial house appeared. One category of them is the Koryŏ temples which revived through Yuan imperial house's temple offering. The Koryŏ temples which revived through Yuan imperial house's temple offering were Pyohunsa(表訓寺), Munsusa(文殊寺), Jangansa(長安寺), Gyeongcheonsa(敬天寺), Jijangsa(地藏寺) etc. and these temples grew receiving a lot of temple offering from the Yuan imperial house. Most of these temples appeared from the reign of King Ch'ungsuk(忠肅). And these temples, rich from Yuan imperial house's temple offering, and protected by political forces were spotted as a hotbed of Buddhist depravity which mass-produced various kinds of social vices at the time. On the other hand, these temples acted as a gateway in receiving the Tibet Buddhist style such as the tower, bell etc.. The periodical limitation of the Yuan intervention period in Koryŏ brought the appearance of Koryŏ temples like this.
