In the "Romance of the Three Kingdoms", the lord of the State of Wu is actually a completely different person from his brother, his brother advocates the value of force, is a small overlord, is a very powerful general, but Sun Quan himself is more elegant, he likes to recruit talents and appoint talents, let them perform their duties, but he also used missed people in his life, so that Eastern Wu embarked on the road of destruction.
It seems that every strategist would recommend his successor to his lord before his death, for example, Zhou Yu recommended Lu Su to Sun Quan before his death, so Zhou Yu reused Lu Su; then, Lu Xun made a great contribution to Eastern Wu, leading Eastern Wu to fight many victories, which was also very powerful, so he recommended Zhuge Ke to Sun Quan before his death.
Zhuge Ke's origin is actually not small, his father Zhuge Jin is a very powerful courtier in the dprk, confucian and peaceful, but Zhuge Ke and his father's personality is completely different, he is irritable and easy to get angry, proud of others and look down on others, never listen to the advice of others, just obstinately, and later because Sun Quan used him, he became more arrogant, but in fact, when he was in a high position, he did not bring any development to the State of Wu.
Later, before Sun Quan died, he entrusted the next emperor to Zhuge Ke, and at that time, Zhuge Ke reached the peak of his power, so he gradually became unable to recognize his own ability, and Eastern Wu after Sun Quan's death had gradually declined, and the State of Wei continued to rise with the help of Sima Yi.
However, Zhuge Ke had not yet recognized the situation at that time and thought that he was very powerful, so he did not want to provoke the State of Wei, so he not only brought unnecessary war to the State of Wu, but also put the State of Wu on the road to ruin, so it can be seen that Zhuge Ke recommended by Lu Xun for Sun Quan was really unfit for the task.
