Ruzi Ying
Ruzi Ying (; 5 – 25), also known as Emperor Ruzi of Han and the personal name of Liu Ying (劉嬰), was the last emperor of the Chinese Western Han Dynasty from 6 CE to 9 CE. After Emperor Ai of Han and Emperor Ping died without heirs, Wang Mang chose the youngest of the available successors in order to maintain his power in the government. The child Ying was soon deposed by Wang Mang who declared the Xin Dynasty in place of the Han. During Xin Dynasty, Ying was under effective house arrest—so much so that as an adult, he did not even know the names of common animals. Before and after the Xin Dynasty was overthrown in 23 CE, many ambitious people claimed to be restoring the Han dynasty. In 25 CE, a rebellion against the temporary Gengshi Emperor used the former Emperor Ruzi as a focus, and when the rebellion was defeated, he was killed. He is often viewed as an innocent child who was the victim of tragic circumstances. (The expression "Emperor Ruzi" is a misnomer, as he never assumed the throne and was only named crown prince. Nevertheless, he is commonly referred to as such.)
Jian'an poetry
The term "Jian'an poetry" covers the final years at the end of the Han Dynasty and during which the Cao family was rising, or risen, to prominence were known as the "Jian'an" era (196-220), the final reign era of Emperor Xian of Han: the following period is known as the Three Kingdoms era, due to the three kingdoms which divided up the Han Dynasty, and war with one another for succession to the Han empire. A prominent Han dynasty general, Cao Cao effectively took control of the Han dynasty from the Liu imperial family, and following Cao Cao's death, his son Cao Pi formalized this by accepting the abdication of the last titular ruler of Han and establishing the Cao family as the ruling dynastic family of a new state, Wei (also known as Cao Wei), one of the Three Kingdoms which were successor states to the Han empire. Besides their role as leaders in war and politics, the Cao family also had an important role in the field of poetry and literature.
