Excuse me, where can I ask M in Shantou (please come up and talk to the soul of the deceased)

This is also called "falling dead ghost". There are all kinds of Haojiang and Chenghai around, generally within 100 days. These psychics had better not ask unless the deceased left too suddenly and didn't tell anyone what happened. It is not so easy to find a soul except those who can't close their eyes. I posted a puzzle post/show-1589114.aspx.
