There was a farmer who always got first place whenever an agricultural exposition was held.
He always handed out his best seeds to his neighboring farmers.
When people asked him for the reason, he said with a smile,
“When wind blows, seeds and pollen are dispersed all over by the wind. If my neighboring farmers grow crops of poor quality, the pollen from the crops will be blown onto my fields and it will lower the quality of my crops. So, my neighbors’ farming is my farming.”
