Why do the locks and keys on the top of Jade Emperor Taishan have to be thrown into the water?

You can bring your own lock. If you buy it, it's 5 yuan each, not expensive, and it's engraved with a name. However, there are not many locks. Have you ever been to Huangshan Mountain? There are many locks. You will be cleaned up by the staff after a while. However, you can lock it, make a wish, and then throw the key off the cliff. All right! Tip: The lock of Huangshan Shimen Gorge was not cleaned. Go and see the lock tomb, haha.
