This story tells us to be courteous. You see, Zhang Ying, the great prime minister of the Tang Dynasty, was so generous and modest, and her virtue has been handed down from generation to generation. So far, Zhang Ying has four valuable points, namely, taking the lead in inheriting the virtues of the Chinese nation that benevolence is beautiful and courtesy is a good neighbor; Be strict with yourself and be lenient with others; It is important not to rely on power, but to be humble and polite; It is not only to set an example, be modest and polite, but also to be good at educating family members and others around them with Confucianism, and to inspire future generations to be generous and treat others with courtesy.

When Zhang Dianying, a great scholar of Qing Dynasty, was an official in Beijing, he received a letter from home one day. After reading it, he understood what happened: it turned out that his neighbor wanted to expand the three-foot courtyard wall, but Zhang Dianying's family refused to give up an inch of land, so there was a quarrel. Helpless, the family wrote to Zhang Dianying, hoping to use his power to intimidate neighbors and stop them from encroaching on the courtyard wall. Zhang Dianying immediately wrote back:

A thousand miles to repair books is just for the wall, why not let him be three feet?

The Great Wall of Wan Li is still there today, but I haven't seen Qin Shihuang.

After receiving the letter, the family immediately gave up three feet of land to their neighbors according to Zhang Dianying's meaning. After learning about this, the neighbors felt deeply guilty and voluntarily gave up their three feet of land, thus forming the famous "Six-foot Lane". This story has become a beautiful talk of tolerance and has been passed down to this day.
