Where was the living Buddha born?

The reincarnation system of living Buddha is a unique form of Tibetan Buddhism. It was discovered through a series of religious trials after the death of a living Buddha. It is considered to be the reincarnation of the living Buddha in the previous area, so there is no concept of time. It depends on the lifetime of the former living Buddha. Tibetan Buddhism is mainly distributed in Tibet, Mongolia, Qinghai, Xinjiang, Gansu and Sichuan, so it will be reincarnated in these areas. In addition, it will be based on what the former living Buddha said when he died.
