The saying “Good people bring out the good in other people” is attributed to Plutarch, an ancient Greek philosopher and biographer.
This phrase suggests that in order to attract excellent talent, one must first be excellent themselves. In other words, if you do great work, you are more likely to attract similarly great people to work with you.
A similar statement was made by Cao Cao in China.
才子相聚，必有异人 （Chinese)
才子は才子を呼ぶ (Japanese)
This phrase means that in order to attract the best people, it is important to be a good person yourself.
“Good wine needs no bush.”
Cao Cao (155 – 220) was a Chinese politician and warlord in the late Later Han Dynasty. He loved learning from an early age and later became active in politics and military affairs, expanding his power mainly in the Zhongyuan region.
Cao Cao is known as a calm and composed leader with a strong sense of right and wrong. He was also well versed in the arts, including literature and music, and was recognized for his talents, leaving behind many literary works and musical compositions.
He was instrumental in unifying China and establishing a centralized political system while waging war against other powers.
