Cai Yong (133–192 CE) was a renowned literary scholar, calligrapher, and musician of the Eastern Han dynasty, and the father of the famous poet and composer Cai Wenji. His courtesy name was Bojie, and he was a native of Yu in Chenliu Commandery (modern-day Qixian, Henan).
When Cao Cao learned that Liu Bei had taken control of Yizhou (Yi Province, modern Sichuan), he realized that unifying the empire would be impossible without securing the strategic corridor of Hanzhong, which lay directly north of Yizhou.
After three long years of terror under Dong Zhuo’s tyrannical rule, the Han Dynasty finally breathed free. In 192 AD, Wang Yun, the loyal minister, and Lü Bu, the mighty warrior, succeeded in their daring plot to assassinate the warlord Dong Zhuo.
