Jia Xu, was an important strategist and advisor during the Three Kingdoms era of China.
Famous for almost killing the Warlord Cao Cao with his stratgies and advices during two battles, and later yet able to switch over to become one of Cao Cao's best and most important advisor.
He is one of my fav personage in the three kingdoms era for his wits and foresight. I always find it to be a pity that a genius like him will ultimately be overshadowed by Zhuge Liang, Sima Yi
This is done for a local card game, General's Order
Luo Guanzhong kind of "overpowered" Zhuge Liang and Sima Yi in the novel unfortunately. He really is one of the greatest strategists from the era. But of course, this drawing and details are amazing as well.
