1, Zou Ji.

During the Warring States Period, Qi Weiwang indulged in pleasure and didn't care about politics. Ministers dare not protest. When Qi people heard about it, they decided to meet it. Taking the piano as an example, he successfully explained the importance of state affairs to Qi Weiwang and was appointed as Prime Minister.

2. Cai Ze.

I am confident that I can rely on the power of words to make Fan Sui, the prime minister of Qin, who won the trust of the king of Qin at that time, give up the position of prime minister to myself. Therefore, he met Fan Sui and introduced himself to Fan Sui. He gave an example of "hiding a bow to save a hundred birds", which made Fan Sui deeply moved and really gave him up to Cai Ze.

3. Mao sui.

During the Warring States Period, Xue Guoren (now from Zaozhuang City, Shandong Province) traveled to Zhao when he was young. As a guest of Zhao Gongzi and Zhao Sheng, he lived in Ping Yuanjun for three years without showing his edge. But in 257 BC, the ninth year of Zhao Haoqi Cheng Xiao's reign, he recommended himself as the ambassador of Chu, which promoted the unification of Chu and Zhao, and won the reputation of "a glib tongue is better than a million teachers".

4. Li Bai

Because Li Bai is a descendant of a criminal, he can't take part in the imperial examination, so he must find another way to be an official. Li Bai once wrote a letter of recommendation to Han Chaozong, but Han Chaozong ignored him. Li Bai's recommendation is of little significance to his official career, but more significance lies in literature, which has added a masterpiece to Chinese literary circles.
