Why did ancient people think of their duties when they listened to cricket and urged people to work hard?

Crickets were called "promoting weaving" in ancient times, because ancient women knew that autumn was coming and winter was not far away, so they should seize the time to weave and make winter clothes. This is the origin of the name "promoting weaving". Then, from here to there, as soon as the ancients heard the crickets, they thought of their duties and urged people to work hard.
