Huche'er (onyomi: Ko Shaji) is a general who served under Zhang Xiu, historically said to have been one of the greatest in his army. When his lord surrendered to Cao Cao, it was said that Cao Cao personally sought for Huche'er and paid gold for the general's new services to him. This apparently caused Zhang Xiu to fear his former general would be used in an assassination attempt on his life, thus relapsing their negative relations and causing the night raid at Wan Castle. Huche'er has no other mentions in historical records.
