诸葛恪
In 221, when the Wu emperor Sun Quan designated his son Sun Deng as crown prince, he set up a staff for the crown prince composed of the sons of key officials in his government or other well-known younger members of the administration. The four most prominent ones were Zhuge Ke (Zhuge Jin's son), Zhang Xiu (Zhang Zhao's son), Gu Tan (Gu Yong's grandson) and Chen Biao (Chen Wu's son). Sun Deng treated the four of them as his close friends and they served as his advisers. When he ordered his secretary Hu Zong () to write a commentary on his advisers in 229, Hu Zong wrote that Zhuge Ke was the most skilful and intelligent of his generation. While this might have been true, Zhuge Ke was also known for being reckless – a negative trait that his father Zhuge Jin repeatedly chided him for. On one occasion, Zhuge Jin observed, "This child will either bring great honour to my household or destroy it."
