Introduction by Liu Xiudian: During his reign, Liu Xiu governed the world with "Judo" and adopted a series of measures to restore and develop social production and alleviate the social crisis since the late Western Han Dynasty. He took various measures to demobilize the local army, organize the army to cultivate land, streamline administration and reduce officials and taxes, which led to social stability, economic recovery and population growth in the early Eastern Han Dynasty. Therefore, Liu Xiu's reign was known as the "Guangwu Zhongxing" in history.
