Meng Po is located in Di Yu (地狱 dì yù) on the opposite side of the Wang Chuan River (忘川河 wàng chuān hé) which can only be crossed by the Nai He Bridge (奈何桥 nài hé qiáo).
After a spirit has atoned for its earthly sins in the 10 Courts of Di Yu, on their way to reincarnation, they must drink Meng Po's Soup (孟婆汤 mèng pó tāng), often translated in English to the "Five-Flavoured Tea of Forgetfulness." The main ingredient of the soup is all the tears the spirit cried on earth, both sad and happy.
When drunk, the consumer will lose all memories of their previous life, and will be ready to take the final path to reincarnation.
