There is a king who rules a rich country. He came all the way from the palace. When he returned to the palace, he kept complaining that his feet hurt. He has never gone that far. This road is very rugged. So the angry king ordered the people to pave every road with leather. At this time, a minister risked offending the king and said, "Your Majesty, why do you spend so much unnecessary money?" ? Why not cut a small leather bag on his foot? The king was surprised to hear the minister's words, but after some consideration, he accepted the minister's suggestion. Moral: It's better to think from another angle.
