It is said that the monk Xuanquan of the Tang Dynasty passed through Fuzhou, the capital of Fujian Province, on his way to Shaolin Temple, and stayed in a hotel, just across the wall. Your official gave a banquet full of incense. The monk smelled it and made his mouth water. He abandoned the Buddha for many years and jumped over the wall to enjoy the "full altar incense." Buddha jumps over the wall, hence the name.
