Bai Mudan (白牡丹; literally White Peony), also romanized as Pai Mu-tan, is a character from Chinese mythology.
[1] It is said that one day, the immortal Lü Dongbin took a walk in Luoyang spotted White Peony, and was attracted to her beauty.
Unfortunately, Lu's immortal colleague Iron-Crutch Li and He Xiangu taught Mudan how to make him ejaculate by tickling his groin.
When Bai's mother consulted with Buddhist Monk Huanglong (Yellow Dragon), he taught her how to make Lü Dongbin ejaculate and thus restore her yin essence.
The Chinese idiom for flattery is duo tun peng pi 掇臀捧屁 (hug the butt and praise the fart) [7] Bai Mudan was deified as a goddess who tempts men or more specifically an ascetic due to her reputation as a seducer.
