English Original
A crow, envious of a swan's beautiful white plumage, thought it came from the water where the swan bathed. So he left the altars where he scavenged for food and moved to live among pools and streams. Despite bathing his feathers many times a day, they grew no whiter. In the end, he died of hunger.

一只乌鸦看到天鹅美丽的白色羽毛，心生嫉妒，以为那是天鹅经常在其中沐浴游泳的水所致。于是，他离开了赖以生存、靠捡拾祭坛上祭品肉屑为生的地方，搬到池塘和溪流边居住。尽管他每天多次清洗自己的羽毛，却没能让它们变白一分。最终，他反而饿死了。
