Chinese emperors family tree (early)
Emperor Xian, the last emperor of the Han dynasty, was a descendant of the first emperor Liu Bang. Lasting for over 400 years (the first to last for more than a century), the Han Dynasty is regarded as one of the golden ages of Chinese history. The Han Dynasty was interrupted by the reign of the usurper Wang Mang, who declared the Xin dynasty (9–23 AD); on this basis, the Han Dynasty is generally divided into the Western Han (206 BC – 9 AD and 23–25 AD) and the Eastern Han (25–220 AD). The rulers of the Shu Han, one of the three successor states to the Han Dynasty during the Three Kingdoms period, were descended from the Han imperial family, and considered themselves a continuation of the Han Dynasty; they are included below.
He Qi
After the end of the Eastern Han dynasty in 220, He Qi continued serving under Sun Quan, who became an autonomous ruler of his Eastern Wu regime in southern China. On the other hand, Cao Cao's son, Cao Pi, usurped the throne from the last Han emperor and established the Cao Wei state in northern China. Between 222 and 223, the Wu and Wei forces clashed at the Battle of Dongkou. The Wei forces led by Cao Xiu defeated the Wu navy led by Lü Fan which had just experienced a natural disaster and lost several ships. Just when the Wu forces were worried about Cao Xiu's impending attack, Wu reinforcements led by He Qi showed up at Dongkou. Since He Qi arrived behind schedule, his fleet was not affected by the storm which destroyed many of Lü Fan's ships. At the same time, as He Qi had a penchant for extravagance, his ships were all finely decorated and his troops were equipped with the best weapons. Cao Xiu was shocked when he saw He Qi's grandeur display of his refulgent fleet. Believing that the Wu fleet was more powerful, Cao Xiu ordered the Wei forces to retreat, thus sparing Lü Fan and his remaining forces from almost certain doom. When Sun Quan heard about this incident, he promoted He Qi to the position of General of the Rear (後將軍).
