The monastery is famous for producing the Trappist milk (known as Cross Milk 十字牌牛奶 or Priest Milk 神父牌牛奶 by Hong Kongers). The factory, however, is now located at Castle Peak, Yuen Long; and the cow farm is said to have been moved to mainland China. Around the monastery some of the last free roaming feral cattle in Hong Kong can be seen, being the descendants of the cattle released after the closure of the dairy farm.
