Fan Wen (Vietnamese: Phạm Văn, Chinese: 范文) was the King of Champa from 336 to 349.
[2][3]: 44–45 Fan Wen has been described as an ethnic Chinese[4] sold into slavery as a child to a barbarian chieftain.
He forged two sabres and prayed, "If I split this rock when I hit it, let the divine virtue embodied in it make me a king."
At fifteen, he fled and sought refuge with a Cham merchant, traveling to Western Jin dynasty of China in 315, before settling in Champa.
He then entered the employ of Fan Yi, using his knowledge of martial art and city fortifications.
