Yà Âm Chang (, ? â ?), also mentioned as Yà Âm Mun, was a Silla general who is best known for assassinating Chang Pogo. Yà Âm had been a subordinate of Chang Pogo, but their relationship apparently deteriorated as he was once punished by Chang Pogo for having been personally engaged in slave trade.
Eventually, YÃ Âm Chang, under the direction of Kim Yang, assassinated Chang Pogo.
