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.)
Cao Jun (Duke of Fan)
In 220, Cao Jun's half-brother Cao Pi became the first emperor of the Cao Wei state after usurping the throne from Emperor Xian, the last emperor of the Han dynasty. The following year, he honoured Cao Jun with the posthumous title "Duke An of Fan" (樊安公). Cao Jun's son and heir, Cao Kang, became the Duke of Fan. In 222, Cao Kang's title was changed to "Duke of Ji" (薊公), and to "Duke of Tunliu" (屯留公) in 223. Cao Kang died in 237 during the reign of Cao Pi's successor, Cao Rui, and was posthumously honoured as "Duke Ding" (定公). He was succeeded by his son, Cao Chen (曹諶), as the Duke of Tunliu. Throughout the reigns of the subsequent Wei emperors, the number of taxable households in Cao Chen's dukedom increased until it reached 1,900.
