Sun Fen (before 235[1] - 270), courtesy name Ziyang, was an imperial prince of the state of Eastern Wu during the Three Kingdoms period of China.
[2] In late January or February 252, he received the noble title "Prince of Qi" (齊王) and took up residence in Wuchang (武昌; present-day Ezhou, Hubei).
[6] Sun Fen became fearful after reading Zhuge Ke's letter so he meekly obliged and moved to Nanchang, the capital of Yuzhang Commandery.
[7] Sun Fen was subsequently stripped of his noble title and reduced to commoner status as punishment for executing a senior official without permission from the imperial court.
[9][10] In 270, the emperor Sun Hao was deeply grieved when his favourite concubine, Lady Wang, died of illness, so he remained indoors for many months and refused to meet his subjects.
