Introduction to Oil Spring, Rice Spring and Longquan: It is said that Guanyin Bodhisattva was transformed by immortal magic to save worshipers from the hardship of climbing mountains. Rice came out of one spring, oil came out of the other spring, and the water flowed in the spring. The amount of rice and oil that comes out is limited to the number of worshipers. If there are more people, more will come out. If there are fewer people, less will come out. There will not be any leftover. But later, a greedy monk wanted to produce more oil and rice to sell, so he dug the entrance of the cave in the middle of the night. As a result, the immortal discovered it and blocked the two caves with stones. From then on, there was no leakage. It’s no longer oil or rice, but the fountain of wisdom is flowing continuously.
