沾沾自喜

西汉时期，窦婴因平定七国之乱而被封为魏其侯。他本是汉景帝的重臣，但因为窦太后的排挤而称病在家。等到七国之乱爆发，汉景帝不得不启用窦婴，并委以重任。窦婴不负众望，成功平定了叛乱。然而，当他被封侯之后，却开始沾沾自喜，不再勤于政事，最终失去了皇帝的信任。

During the Western Han Dynasty, Dou Ying was appointed Marquis of Weiqi after suppressing the rebellion of the Seven States. He was an important minister of Emperor Jing of Han, but was sidelined by Empress Dowager Dou and feigned illness to return home. When the rebellion of the Seven States broke out, Emperor Jing had to appoint Dou Ying again and entrusted him with important responsibilities. Dou Ying lived up to expectations and successfully quelled the rebellion. However, after being enfeoffed as a marquis, he became complacent, no longer diligent in his official duties, and eventually lost the emperor's trust.

常用来形容人自以为是，洋洋得意，对自己的成就沾沾自喜。
