Zhuge Liang (181-October 8, 234), courtesy name Kongming, nickname Wolong (also known as Fulong), Han nationality, native of Langya Yangdu, Xuzhou (now Yinan County, Linyi City, Shandong Province), prime minister of the Shu Han Dynasty during the Three Kingdoms period, outstanding statesman, strategist, essayist, calligrapher, and inventor. He was named Wuxiang Marquis when he was alive, and Zhongwu Marquis after his death. The Eastern Jin Dynasty regime named him Wuxing King because of his military talents. His representative works of prose include "Chu Shi Biao", "Book of Commandments", etc. He invented the wooden cow and flowing horse, the Kongming lantern, etc., and modified the repeating crossbow, called the Zhuge repeating crossbow, which can fire ten arrows with one crossbow. He died in Wuzhangyuan (now Qishan, Baoji) in the 12th year of Jianxing (234).
Liu Chan gave him the posthumous title of Zhongwuhou, so later generations often addressed Zhuge Liang as Wuhou and Zhuge Wuhou. Zhuge Liang "dedicated his life to death" and was a representative figure of loyal ministers and wise men in traditional Chinese culture.
Zhou Yu (175-210), courtesy name Gongjin, was a famous general in the late Han Dynasty and a native of Shu County, Lujiang (southwest of today's Lujiang County, Anhui Province). Luoyang ordered Zhou Yi's son, his grandfather Zhou Jing and his uncle Zhou Zhong, both to the rank of Taiwei. He is long and strong, has good looks and fine music, and there is a saying in Jiangdong that "if the music is wrong, Zhou Lang will take care of it". Young Master Zhou Yu had a good relationship with Sun Ce, and he followed Sun Ce to the battlefield to pacify Jiangdong from the age of 21. Later, Sun Ce was assassinated and Sun Quan succeeded him. In the 13th year of Jian'an (208), Zhou Yu led the Sun Group's army in Jiangdong to join forces with Liu Bei's army, and defeated Cao's army in the Battle of Chibi, thus laying the foundation for a divided world. In the 14th year of Jian'an (209), he worshiped the partial general as the governor of Nanjun. He died of illness in Baqiu (now Yueyang, Hunan) in the fifteenth year of Jian'an (AD 210) at the age of 36.
In the official history, Zhou Yu has a "magnificent personality" and "a real genius", and Fan Cheng praised him as "a heroic man in the world and a romantic and beautiful husband on the left side of the Yangtze River". During the reign of Emperor Huizong of the Song Dynasty, he was honored as Pinglubo. Ranked among the 64 generals in the Tang Wumiao Temple and one of the 72 generals in the Song Wumiao Temple.
