The water of Bodhi Yang originally meant the divine water in the pure bottle of Guanyin Bodhisattva. This is an allusion in The Journey to the West. It's about the Monkey King knocking down the ginseng tree, which caused the Tang Priest to get into trouble and traveled all over the three islands, but no one could cure him. Finally, I found Guanyin Bodhisattva and saved the ginseng fruit tree with the holy water of Yujing bottle. This is the hope of getting the water of Bodhi Yang. This sentence is used to describe the meaning of finally getting a result after a lot of hardships.
