Be grateful and learn the words of gratitude.

Filial son is the greatest respect for relatives; Respect for relatives is nothing more than raising the world. -Mencius

Mourn for my parents and give birth to me. -The Book of Songs

Once a teacher, always a father.

Who can say that a filial child like the weak can repay his mother's love like the sunshine in spring?

Accept a drop of water when necessary, and I will repay your kindness with spring water.

It's great to repay kindness with kindness.

Sheep have the grace of kneeling and nursing, and crows have the meaning of feeding back.

Learn to present Momo with thousands of rivers and lakes.

Catch me, and I'll catch you.

One father raises ten children, and ten children raise one father.

Look down on the world and remember that kindness is like blood.

Fish know that water is the source of happiness.

Grace wants to repay kindness, resentment wants to forget; Short complaints are long rewards.

Do your best until you die. (Zhuge Liang's "Model")

Crows have the intention of feeding back, and sheep know the grace of kneeling and nursing.

Accept a drop of water when necessary, and I will repay your kindness with spring water.
