Sypnosis
Born in the Jin province’s Bailu county, a villager of Baishui village. A plague broke out in Bailu county during Jingjia First Year, when Qi Yan was fourteen years old, emptying nine houses out of ten. The Qi family of six escaped towards the north, unfortunately encountering mountain bandits in their journey. Qi Yan suffered from two blade injuries and was saved by a skilled person, but died later from illness.

Who knows if it was a coincidence or a man-made one; all of Qi Yan's relatives had died in the next few years.
