I've been to this park. Seen some things you wouldn't believe. Monkeys begging for a biscuit then taking the whole bag. Monkeys stealing popsicles from kids. A monkey getting a pepsi from a vending machine and opening the plastic bottle with its teeth. Swole bro monkeys showing off their pecs and asses to tourists. Herds of monkey kids running through the underbrush while park staff could only look on or sometimes try to scare them off with slingshots. Macaques don't care. They are the majority here. They rule the park.
I heard that when guiyang had a minor lockdown, the macaques that were used to stealing treats from visitors had to go hungry, and then went down from the mountain park into the city below to get their treats one way or the other
