Tianjin Vitality Source Black Powder is an MLM organization. The reason why black coarse cereals powder has such magical effect is that its founder Song Deshun met a Taoist in his early years. Seeing that Song Deshun was skinny, the Taoist priest taught him a secret recipe of Taoist medicine and named it Qingshen Dan. Later, Song Deshun not only used this elixir to recuperate his body, but also made the formula into black miscellaneous grains powder for the benefit of the whole people.

Ironically, Song Deshun, who holds the "God's Prescription" that can cure almost all diseases, is worried about the sufferings of ordinary people, but he can't "help himself" while "helping others".
