Liu Bang, Emperor Gaozu of the Han Dynasty, adopted the advice of Sean, the most authoritative geomantic master in China, and designated Chang 'an as the capital. Sean (about 250 BC-BC 186), born in the Han nationality, was the father of the city in the early Han Dynasty and is now the father town of Bozhou. Liu Bang, the counselor of Emperor Gaozu of Han Dynasty, was an outstanding strategist and politician at the end of Qin Dynasty and the beginning of Han Dynasty, and one of the founding fathers of Han Dynasty. The so-called "strategizing, winning thousands of miles" refers to Sean. Sean is famous for "seeking the holy".
