i'm here to meet ho loy, a conservationist who's dedicated her life to taking care of another bovinee water buffalo. we're going to have a long day. are you ready for it? i think so. i'm ready to get my hands dirty, help the buffalo. this is the eco farm i grow. we bring the community here to take class and learn from us what the ecosystem is about. the hong kong people mostly are urbanisers. they don't quite understand what nature is about. so, we get their hand in touch with soil and plant and get dirty. we need to pack this bag, like, heavily pack. i'll give you 20 minutes. so all of this. all of this? all of this grass? yeah. so what do these animals mean in chinese culture? we have 12 animals, but cow, tiger, chicken, pig are all real animal. they represent a value, a cultural value in our history. so the cow to me is the most important species among all of them. yep, loy is a serious... ..taskmaster. be worth it, though. hi, guys! we're going to start going now. ijust need a bag. it's time to serve lunch, but where are all the water buffalo? i'm going to call the buffalo now. y
