Doctor Chu meditated and died without regret; Wei Wudi pointed the whip to the east with great courage; Tao Yuanming carefree Nanshan, drinking and picking chrysanthemums ... they chose eternity, even if they flatter and slander, they don't follow, which is a persistent choice; Even if the horse dies, it is only a hero's choice; Even if you are poor and have no food all day, you are willing to take pleasure in it and devote yourself to farming. This is an elegant choice. Some choices, emperors will become their great achievements, sages will touch their guests and become their eternal articles.
