Strangers to Linhai City, Zhejiang Province are always curious about the bottled yellow liquid in the market. To their surprise, it is not the fruit juice but the fresh ginger juice. Ginger can be used to keep the body warm, thus traditionally people eat it on winter solstice by the lunar calendar. If you just gulp the ginger juice, you would burn your stomach. The best way to drink ginger is to boil and skim it, adding mince, custard, Huangjiu (yellow wine), brown sugar, and walnut. Steam it until done. If you can stand the hot ginger, you would sweat so much that you feel cold is gone. In this way, you will be healthy the whole winter.  

Another tradition in Linhai City is that ginger juice must be drunk during the confinement. The tradition can be passed on because it is really the right thing to make you healthier. The benefits of ginger are written in the medical book Compendium of Materia Medica by Li Shizhen, a great doctor in ancient China.
