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.
Cao Cao Mausoleum
During the forum, Lin Kuicheng, a historian and member of the China Federation of Literary and Art Circles, pointed out that Cao Cao should not be referred to as "King Wu of Wei" before 220 CE. After Cao Cao died in March 220 CE, his vassal king title – "King of Wei" – was inherited by his son, Cao Pi, who continued to hold the title until around December when he forced Emperor Xian, the last emperor of the Han dynasty, to abdicate in his favour. Since Cao Cao was buried about one month after his death and his funeral was most likely presided over by Cao Pi, it would be taboo to refer to Cao Cao as "King Wu of Wei" because the "King of Wei" (Cao Pi) was still living then. Furthermore, when Emperor Xian relinquished his throne to Cao Pi, he referred to Cao Pi and Cao Cao as "King of Wei" and "King Wu" respectively in his official abdication edict; Cao Cao was never referred to as "King Wu of Wei" in the edict.
