I’m seeing stories like that but that hasn’t ever been my experience. I also keep a respectable distance and use my zoom to get good pictures. Patients is a virtue and I was also told not to smile at them. They don’t like teeth.
I assume this is Kaosiung. One time I was visiting a campus there that had these monkeys. It was hell and pure entertainment. These monkeys were on parked cars and people couldn't leave for hours. If they tried to get in their cars the monkeys would attack. And couple came by and the girl had a water bottle so the monkeys attacked her and the boyfriend just bounced and ran off to the hills while his girl was having her hair ripped out.
I saw this all while I was waiting for my bus. When the bus came and people got off, the unfortunate people on the bus didn't know there were monkeys and many were carrying plastic stuff in their hands. The monkeys started attacking all the pasaangers getting off. Unfortunately we had to get on the bus and it was pure mayham trying to get on the bus during a monkey ambush.
