Baoyuan decoction is a kind of health care and beauty soup created by Dr. Liu during the reign of Qing Qianlong. It is said that drinking this special Baoyuan soup often can make the skin smooth, without wrinkles and age spots, and make the skin delicate and clean as jade. Later, it became the favorite beauty and health care soup of Empress Dowager Cixi.

How to make it: The ingredients of each Baoyuan soup are one catty of live crucian carp, half a catty of lean beef, one big pig's trotter, one or two raw hawthorn, ten small red dates and five things. The method is to wash crucian carp, remove scales and viscera, wash and chop half a catty of lean beef, wash and remove hair from pig's trotters, and remove stones from raw hawthorn and jujube. Then add two liters of water to the five things, cook them on low fire for one day, remove the residue, keep the clear soup, and then freeze them overnight. The next morning, remove the solidified oil slick from the soup, heat it again, and then drink a bowl in the morning, noon and evening.
