A large part of the work of the Trappists is concerned with their dairy. The cows are fed regularly, milked and kept healthy. The dairy, which produces about two thousand bottles of milk a day, brings the monks their main income. The monks sell about half of the milk to a large hotel in Hongkong, while hospitals and schools buy the rest. The monks also earn some money by selling eggs. Sometimes, the Trappists sell some of their cattle. The monks themselves do not eat meat, however, as they are vegetarians.
