Liu Yan (Wei)

Biography & Historical Record

Liu Yan (Wei) (刘延, Lưu Diên) (dates unknown) was Administrator of Dong Commandery (东郡, Đông Quận) under Cao Cao (曹操, Tào Tháo) during the late Eastern Han. Stationed on the Yellow River frontier at Baima (白马, Bạch Mã), he held the northern gate of Cao Cao’s base while Yuan Shao (袁绍, Viên Thiệu) pressed south. He is not the Yi Province warlord Liu Yan (刘焉, Lưu Yên) (id 3838 /liu-yan/) — different hanzi, era role, and slug liu-yan-wei.

In 200 AD Yuan Shao’s vanguard under Yan Liang (颜良, Nhan Lương) besieged Baima. Liu Yan held the walls and sent urgent appeals to Xuchang. Cao Cao marched to relieve him; Guan Yu (关羽, Quan Vũ) rode into Yan Liang’s ranks, took his head, and broke the siege — a pivotal early stroke of the Guandu campaign. Historically the stand at Baima bought Cao Cao the time to counterattack; literarily it frames Guan Yu’s first great exploit in Cao Cao’s service.

Role in Romance of the Three Kingdoms

Chapter 25 (Besieged in Tushan, Guan Yu Makes Three Conditions; Relieved at Baima, Cao Cao Breaks the Siege): Yan Liang’s host surrounds Baima. Wei officers Song Xian (宋宪, Tống Hiến) and Wei Xu (魏续, Ngụy Tục) fall or fail in combat; Xu Huang (徐晃, Từ Hoảng) cannot turn the tide. Liu Yan watches Guan Yu gallop down, spear through the enemy front, and return with Yan Liang’s head — lifting the siege that had nearly crushed Dong Commandery.

Chapter 27 (The Beautiful Beard Rides Alone a Thousand Li; Guan Yu Slays Six Generals Across Five Passes): Escorting Lady Gan (甘夫人, Cam Phu Nhân) and Lady Mi (糜夫人, My Phu Nhân) toward Liu Bei (刘备, Lưu Bị), Guan Yu reaches Dong Commandery. Liu Yan greets him with honour for the Baima debt, yet refuses a ferry across the Yellow River: the crossing is guarded by Qin Qi (秦琪, Tần Kỳ) under Xiahou Dun (夏侯惇, Hạ Hầu Đôn), and Cao Cao’s permit law forbids private passage. Reminding Liu Yan of Yan Liang’s head brings only an apology — fear of law, not ingratitude. Guan Yu proceeds to the ferry and slays Qin Qi himself.
