How does Tibetan Buddhism choose living Buddha?

First of all, the living Buddha was not elected by voting, but reincarnated. The old living Buddha sometimes showed people the way and told him where to be reincarnated. If he doesn't specify, then according to his behavior before his death, such as the place he often mentioned, or the direction he faced when he died, etc. There is a special procedure for reincarnation of living buddhas, including foretelling. The following are the unique astrology and lake-watching techniques of tantric school. Divination mainly looks at the place where the living Buddha was born. After confirmation, monks are sent to find eligible children (such as those born on the day the living Buddha died). If there is more than one qualified child, it will be determined by testing. The first is to see the kindness of the place where the child and the old living Buddha lived. The second is to mix the things used by the old living Buddha with other things for children to master. Finally, the formal procedure is: draw lots to decide the golden urn. Write their names on the sign, put them in the golden urn, and then draw lots to decide who will be the living Buddha.
