Meng Po

Meng Po (Chinese: 孟婆; pinyin: Mèng Pó; Wade–Giles: Meng-p'o; lit.

She awaits the dead souls at the entrance of the 9th round Fengdu (Chinese: 丰都; pinyin: fēng dū).

It is her task to ensure that souls who are ready to be reincarnated do not remember their previous life or their time in hell.

In Chinese tradition, there are legends of miracle births, where a newborn is able to speak because the soul of the baby didn't drink the Five Flavored Tea of Forgetfulness.

Occasionally people are able to avoid drinking the brew, resulting in past life memories surfacing in children.
