In ancient times, Gou Jian, the king of Yue, was determined to take revenge. In order to sharpen his ambition and not forget his humiliation, he hung gall indoors and must taste it before eating. When you sleep, you should put firewood under your body to keep yourself alert. You can't be prepared for danger in times of peace and lose the determination to avenge yourself. He personally worked with the people and let his wife weave clothes, eat without meat and wear without decoration, and share joys and sorrows with the people. After a long and arduous struggle, Yue finally rose again from failure after "ten years of reunion and ten years of lessons". In the summer of the thirty-eighth year of the Zhou Dynasty (482 BC), Gou Jian, the king of Yue, took a trip by ambush and led an army to attack Wu, defeating Wu Shi and Wu Du. In the fourth year of Zhou Yuanwang (473 BC), Gou Jian attacked Wu again, defeated Wu Jun, and Fu Cha committed suicide. Since then, Zhou Yuanwang made Gou Jian a "Bo", that is, he was the head of the vassal, and Gou Jian dominated the vassal.
Old people often say, "You will get people if you eat hard." If you don't work hard, you can only be eliminated by this society, so learn to endure hardship, learn to endure and learn to work hard. Although there is a spirit of "suffering", it is not necessarily a "master". As long as you work hard, you can have a clear conscience regardless of the outcome.
