community will organise the activity. All residents they are interested in farming are invited to

take part the activity. Weather permitted, we’ll ride bike to do some farming this Saturday on a

farm. It is about 5 kilometres far away from our community. You can grow some vegetables,

plant some flowers and fed fish in the lake nearby. You will be trained and guide while

farming. Not only will you enjoy the pleasure of labour and get relaxed, but also you can taste

some fresh produce unless you are willing to. Everyone is welcome to attend!
