Zhang De, male, 1974, from Binyang, Guangxi. He was born with a disability in his right hand and writes with his left hand. From 65438 to 0994, he was admitted to Jiaxing College, and from 65438 to 0997, he was assigned to Chenping Township Cultural Station in Binyang County as the stationmaster until he resigned at the end of 2003. 200 1 On the 15th day of the seventh lunar month, Zhang De began to specialize in Liuyi. Since 2007, we have made great efforts to solve the fallacies of the ancient and modern six-hexagram books, and for the first time made public the concise, practical and accurate six-hexagram correct way, that is, the "hexagram method" system. Since 2008, the representative works "Absurdity of Authentic Divination" and "Absurdity of Buyi Addition and Subtraction" have been published in Taiwan Province Province. "Don't be superstitious about authority, don't be superstitious about yourself, and only obey the truth" is Zhang De's unswerving principle.
