Story:
During the Three Kingdoms period, after Emperor Wen of Wei, Cao Pi, died, Sima Yi and Cao Shuang became regents for Cao Rui.
After Cao Rui's death, Sima Yi eliminated Cao Shuang.
Later, Sima Shi, Sima Yi's son, installed Cao Mao as the new emperor.
However, Sima Zhao, Sima Shi's younger brother, paid no respect to Emperor Cao Mao and even threatened to be granted the title of Duke of Jin, which was a clear sign of his ambition to usurp the throne.
Outraged, Emperor Cao Mao famously exclaimed, 'Sima Zhao's heart, everyone on the street knows!' meaning Sima Zhao's treacherous intentions were obvious to all.
