Origin Story
商汤伐桀，得胜后，巡视战场，看到一个猎人用四面网捕猎飞禽走兽。商汤问猎人：‘你的网四面都张开，岂不是所有飞禽走兽都跑不掉吗？’猎人得意洋洋地说：‘是的，所有的动物都跑不掉。’商汤听了之后，笑着说：‘这样，未免太残酷了些！’于是下令拆掉三面网，只留下一个缺口，让部分飞禽走兽可以逃脱。
After the victory over Jie, Shang Tang inspected the battlefield and saw a hunter using a four-sided net to hunt birds and animals. Shang Tang asked the hunter: 'Your net is open on all four sides, doesn't that mean that all birds and animals cannot escape?' The hunter proudly replied: 'Yes, all animals cannot escape.' After hearing this, Shang Tang smiled and said, 'This is a bit too cruel!' So he ordered the removal of three sides of the net, leaving only one opening to allow some birds and animals to escape.
