Big monkey in zoo

Last year i went go Africa with my family and then i went to the Zoo. The Zoo is near my hotel in there have a lot of animals like Gorilla , tiger,lion,elephant, etc....., but in there have a one monkey is very large.The people in those country call those monkey the king of monkey . Those monkey is stronger so the cage they need make the cage from stone . Some people in there tell me those monkey ever tear the cage because the cage before it is made from metal when it kid it look so small but when it have 20 year old is large.Monkey eat meat like goat meat cow meat or a lot of animal but some it eat banana . The worker do work in zoo when they feed meat to those monkey they a feel scare and afraid those monkey eat they but those monkey i look i think it don't want to do anything with someone because it have long life.i hope those monkey can live a long time
