It is an idiom in China to win without arrogance and lose with grace. Pinyin means she ng bàI bùnīI ā o, b à i b ù n and i, which means you can't be proud if you win, and you can't lose heart if you lose. Shang Jun's book of tactics says: "The king's soldiers win without arrogance and lose without resentment."
A famous saying about winning without arrogance and losing with grace:
1. We can't jump high as soon as we get results, just like a ball that others can't shoot. The greater the achievement, the more modest and prudent you should be. -Wang Jinxi
2. Virtue is based on people who are always empty. -Fang Xiaoru
Modesty makes people progress, while pride makes people lag behind. We should always remember this truth. Mao Zedong
