In the Spring and Autumn Period, Confucius, Mencius, and Zhuangzi all sold courses. They only talked but did not work. They only sold opinions, and finally all became gods. Su Qin, Zhang Yi and other people were consultants. They gave the emperor advice and ignited the emperor's dream. If the emperor did well, he would be given a high position and a generous salary. If he did not do well, he would run away and continue to fool other emperors.
Shang Yang, Wu Zixu, Han Fei, Li Si, and Wang Anshi were the most miserable. They were responsible for the whole case and exhausted all their efforts. If it succeeded, the birds were gone and the good bows were hidden. If it failed, the emperor would be punished and Chao Cuo would be executed. The whole case was dead.
Selling courses is the choice of the wise. They are not responsible but only solve doubts. Consulting, win with wisdom, and basically you can live a stable life without taking responsibility. The whole case, implementation, are all risks. Doing operation and operation is a life of licking blood on the edge of a knife.
The ancients had no time to mourn themselves, but later generations mourned them; later generations mourned them but did not learn from them, which also made later generations mourn later generations.
