Bull Joy, also known as tripe, refers to the stomach of a bull and is a traditional Chinese food ingredient. Bullwhip, on the other hand, refers to the reproductive organs of a bull, usually the penis and testicles of a bull.

Bull's merriment is rich in collagen and a wealth of nutrients, such as protein, calcium and iron, and is widely used in cooking a variety of dishes and soups. Bullwhip has the effect of nourishing and aphrodisiac, so it is widely used as herbal medicine in some Asian countries and made into a variety of health products, medicines and food additives.
