Chu-ke Liang continued,"Ts'ao Ts'ao's soldiers come from another region and are not used to naval battles.Our people in Chingchou City hate Ts'ao Ts'ao and his men.Given these facts,if you make an alliance with Liu Pei,we together will surely defeat Ts'ao Ts'ao.Then Ts'ao Ts'ao will retreat to the north.You can keep the area southeast of the Yangtze River, and Liu Pei will take back Chingchou City.Then there will be three independent Kingdoms.Now is the time to make your decision."
