It is said that cows will fly when they blow hard. Is it true?/You don't say.

Yes, it is said that there was a poor scholar walking on the road in ancient times. He saw an old cow walking slowly on the road in the distance. It was very hard and he felt sorry for the old cow.

So he had a whim to let the old cow fly in the sky, so that he could save some strength and walk less laboriously and slowly. Finally, he caught up with the old cow in three steps and gave it a strong breath. As a result, the old cow really flew, and he was very happy.

I suggest you increase your strength. If you can't blow, you may not be strong enough.
