What talented and immoral traitors were there in ancient China, whose works were well-known but infamous?

There were many talented and immoral traitors in ancient China. Their works are well known, but they are notorious. They are Yan Song, Cai Jing and Qin Gui. A person's talent is important, but if there is no good moral character to support his talent, then this person will inevitably be cast aside, not only in ancient times, but also in modern times. Only people with both ability and political integrity will be admired by everyone.

Yan Song is really a talented person. He has been very clever since he was a child and is eager to learn. He won an award at the age of 19. At the age of 25, he passed the imperial examination and entered imperial academy. From then on, Yan Song was very smooth, good at reading minds, and good at flattering others. Most importantly, he is also ruthless, and he has always done whatever it takes to achieve his goal.

Cai Jing is also a treacherous court official, even as insidious as Gao Qiu. Cai Jing received a good education since childhood, but he used all his knowledge to persecute people, eradicate dissidents and seek common interests. He can be said to be the chief culprit of political corruption in the Northern Song Dynasty. Cai Jing, such a big traitor, is also a great calligrapher. His calligraphy is very beautiful, even ranking first in the world.

When it comes to Qin Gui, I think everyone must know that he is a traitor worthy of the name, and he is also a traitor. He once framed General Yue Fei, and I think many people will hate his teeth when they think about him. Everyone's impression of Qin Gui is mostly treacherous and despicable, but in fact, he is also a very learned man with high attainments in calligraphy. The style of songs was actually created by Qin Gui.
