Introduction to the Eight Hundred Cloud Ladder: The Eight Hundred Cloud Ladder was built in 1988 when Foguang Mountain was first developed, with a total of 810 steps. There is a saying in the Buddha's saying: Ninety-nine things will return to one, and they will eventually achieve the right fruition. It means that you have to go through eighty-one tribulations on the way to practice, before you can understand your mind, see your nature, and achieve Buddhahood. Nine-Nine Returns to One also represents the cycle of nature, coming from the beginning, going out, and returning to the original state.
