Liu Ying, Prince of Chu, who was Emperor Guangwu's son and Emperor Ming's elder brother, was charged in connection with the rebellion against his brother. Thousands of people were implicated, and severe punishments were meted out. To a large extent, the accusation was groundless: Emperor Ming merely used the incident to serve its political purpose. Liu Xiu loved Yin Lihua since his youth: he married her when he joined the rebellion against Wang Mang, who had usurped the throne. Then, Liu Xiu was sent to the arca north of the Yellow River, where he built his own military force and finally declared himself Emperor Guangwu. In the second year of his reign (A.D. 26), Emperor Guangwu appointed Guo Shengtong, one of his concubines as the empress, because at that time in his harem she was the only woman who gave birth to a son. The boy, Liu Qiang, was the designated successor. However, in the seventeenth year of his reign (A.D. 41), Emperor Guangwu deposed Guo and appointed Yin as empress. The eldest son of Guo, the immediate successor to the throne, suffered the same fate as that of his mother, while the eldest son of Empress Yin became the heir apparent instead. These political upheavals caused a tense atmosphere among the princes. Liu Ying's mother, Xu, was an inconspicuous concubine of Emperor Guangwu, and Liu Ying was her only son. As a result, Liu Ying was actually isolated and helpless among his brothers; he was victimized on account of the bad relation between his brothers.
