Tofu has a long history. According to legend, it was invented in 164 by Liu An, the grandson of China's great-grandfather Liu Bang. When Liu An was burning medicine and alchemy on Bagong Mountain at the junction of Shouxian County and Huainan, Anhui Province, he accidentally ordered bean juice with gypsum, thus inventing tofu.

Tofu is a nourishing, heat-clearing and health-preserving food. Regular eating can tonify the middle energizer, clear away heat and moisten dryness, promote fluid production to quench thirst and clear the stomach. It is more suitable for people with heat constitution, bad breath, thirst, indigestion and fever. Modern medicine has proved that tofu not only has the functions of increasing nutrition, helping digestion and stimulating appetite, but also is beneficial to the growth and development of teeth and bones.
