The Meng Po soup prepared by Meng Po requires the tears left by the reincarnated person. There are eight tears as a guide: one drop of raw tears, two cents of old tears, three points of bitter tears, four cups of tears of regret, five inches of tears of lovesickness, six cups of tears of illness, and seven feet of tears of separation. This eighth taste is Po Meng's tears of lovesickness.
If one of the eight tears is missing, he becomes a tearless soul. This tearful soul cannot be reincarnated, and cannot be reincarnated. It must find the tears of a stranger whose birth date and horoscope match it, so that it can be reincarnated.
It's just that people are separated by yin and yang. How can we find it? How can we make strangers shed tears of birth, old tears, bitter tears, regrets, lovesickness, sickness, and farewell?
