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.)
Cheng Yu
Cheng Yu (141 – December 220), originally named Cheng Li, courtesy name Zhongde, was an official who lived during the late Eastern Han dynasty of China. He was an adviser to Cao Cao, the warlord who became the "de facto" head of the Han central government during that period. He died in December 220 – a few months after Cao Cao's son, Cao Pi, usurped the throne from Emperor Xian (the last Han emperor) and established the state of Cao Wei, an event marking the start of the Three Kingdoms period in China. Cheng Yu was described as a tall man (approximately 1.91 metres) with a beautiful long beard. He was from Dong'e County in present-day Shandong. He was best known in his time for his abnormal approach to cope with a shortage of grain: instead of sending hostages to Cao Cao's rival, Yuan Shao, in exchange for food supplies, he advised Cao Cao to feed his army with human flesh. He was also noted for his expertise in military tactics, which helped Cao Cao defeat Yuan Shao at the Battle of Guandu in 200 and consolidate control over northern China. It is widely agreed that his numerous contributions laid the foundation of the Cao Wei state; the reason he was not promoted to the rank of a duke was only because of his aforementioned strategy to cope with the food shortage in Yan Province. After Cheng Yu's death, Cao Pi honoured him with the posthumous title "Marquis Su", meaning "solemn marquis".
