The so-called hungry people meet food, that is, the hungry people meet food. Two layers of metaphor:
First, you are not in a hurry to choose dishes. Although you are full, it will increase your abdomen and cause other discomfort. So although some things are needed, greed will damage them.
Second, if you have food and enjoy it slowly, you can also solve hunger. Therefore, if necessary, if you take it in moderation, it will last forever.
