馬騰
Not long afterward, however, Han Sui and Ma Teng's relationship soured and the two of them battled each other for control of Liang Province. Their battle escalated to the point where both were killing each other's wives and children. Cao Cao, having achieved victory at the Battle of Guandu in 200CE, sent Zhong Yao to broker a peace between the two sides and to place Liang Province under Cao Cao's authority. After the terms were agreed to, Han Sui and Ma Teng would give assistance to Cao Cao in the remainder of his battles against Yuan Shao. After this, Ma Teng was forcibly summoned to Ye and Han Sui placed Ma Teng's son Ma Chao in charge of Liang Province.
