and I have a story to share about my experience with 'tan ki'.
Long ago, I have a friend who suddenly got possessed and said he was chosen by the '3rd prince'. Since then he work as 'tan ki' for some days at night in Eunos. I wasnt a believer in these thing, so 1 night we a group of friends went to see. And strange enough, everyone claimed that they saw their previous life when they were shown a wooden plate, but only I cant see anything? I proceed to ask to speak to my father (passed away long ago). 'tan ki' rejected say this will shorten the boy's live. So i wont insist.
After some time, i heard from that group of friends, that the 'tan ki' no more, 1 night suddenly 'tan ki' announced that he is not the '3rd prince', but some ghost and laughed at the people there that ghost words also believe.
