Cheng Kuang - in Romance of The Three Kingdoms - Chapter 45

Chapter 45

• Cai Xun (蔡勳), Cai Mao's younger brother. He originally served Liu Biao but later served Cao Cao after Liu Biao's successor Liu Cong surrendered to Cao. He was killed by Gan Ning in a skirmish between the forces of Cao Cao and Sun Quan before the Battle of Red Cliffs.
• Cai He (蔡和), Cai Mao's cousin. He served Cao Cao after Liu Cong surrendered to Cao. He pretended to defect to Sun Quan's side while serving as a mole for Cao Cao. Sun Quan's viceroy Zhou Yu knew that he was a spy and used him to spread false information in the enemy camp, leading to Cao Cao mistakenly believing that Cai Mao and Zhang Yun were planning to betray him. He was executed by Zhou Yu just before the Battle of Red Cliffs.
• Cai Zhong (蔡中), Cai He's brother. He also spied on Sun Quan's camp together with his brother, and was executed by Zhou Yu just before the Battle of Red Cliffs.
