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.)
Han Eum
Han Eum () also known as Han Do () was one of the four members (No In, Han Eum, Sam and Wang Gyeop) who operated the government of Wiman Joseon. His position was a chancellor. Since Han Eum had a family name, Han, it is believed that he was an exile from China or person related to China. Just like his master Ugeo who was the last king of Wiman Joseon.　In BC 109 to 108, when Han dynasty attacked Wiman Joseon, he was surrendered instantly together with those exiles from China, No In and Wang Gyeop, while leaving the King of Wiman Joseon Ugeo. After his surrender, Han dynasty nominated him as a peerage of Jeok ja (Hangul:적자 Hanja:荻苴). He died after 19 years without a successor.
