Near Lingshan mountains there is a small buddhist temple built inside of a cave. They had a theory that it was where the earth ended. It was almost if they never looked further then the giant mountain. Furthermore there was a tree where if you went around it once you lived for 99 years, I went around twice. I don’t know if it is cancelled out because I went twice or doubled but I will let you guys know in either 198 or 99 years.
