Yue Guang was born to a poor family and lived in the lowest social class, but was appreciated by several high-ranking government officials due to his moral integrity and ability in his childhood.

After the kingdom of Wu was eliminated to improve the poor situation left by the war, Sima Yan took Luoyang as his capital and adopted a series of measures throughout the country, such as focusing on agricultural production and protecting the interests of the gentry.

After being familiar with him, Xiahou Xuan said to his father, "Yue Guang will become a famous officer in the future, it is rare to behave so decently in his age.

[9] Yue Guang served as county magistrate of Yuan City and was promoted to being the princess's tutor, then later the master of Henan.

While evaluating employees, Yue Guang preferred to point out their advantages first, then the disadvantages would be realized by themselves without mentioning it.

[11] In the first year of Yongkang (300 AD), Sima Yu, known as the crown prince Minhuai, was deposed and detained in Jinyong City.

Those people could do nothing but sigh indignantly, but eventually, all of them decided to violate the decree and went to worship, and the government clerk arrested them and sent them to jail.

One of the assistant prosecutors said to the manager, "The reason why the prince was deposed is he overused his authority and enjoyed luxury every day.

Despite his protests, Yue Guang could not convince Sima Ai otherwise, which added to his mental pressure and resulted in some psychological problems.

His friend explained that he felt extremely uncomfortable after having dinner with Yue Guang in his house since he thought there was a snake in his cup while drinking.

At midnight, he stayed in the palace with some soldiers and the door suddenly opened following some harsh and menacing noise, everyone was scared at that time except Yue Guang.

When Wang Cheng and Hu Wufuzhi served as high officials, they almost did whatever they wanted, such as streaking and insulting others.
