Yesterday, Wuhan Zoo Monkey caretaker Zhang Bangsheng unbelievably used his tongue to lick a small monkey’s butt!

50-year-old Zhang Bangsheng used warm water to clean a small Francois’ Leaf Monkey’s buttocks, then began using his mouth to lick it, not stopping for over an hour, until the little monkey defecated a single peanut. Only after the peanut was defecated did Zhang Bangsheng laugh with satisfaction.

As it is understood, this small Francois’ langur is only 3 months old, and is the first Francois’ Leaf Monkey to be born in nearly 10 years at this animal park. The Francois’ langur is a rare primate from Guangxi and Guizhou and is amongst the nation’s most protected animals. Because it is so precious, the zoo gave it to model worker and high-level expert Zhang Bangsheng to care for and raise.
