Three generations of gentlemen. Small trees cannot grow without pruning.
Children can't grow up without raising them, and trees can't grow up without raising them.
Whether children are taught or not, trees can't be cultivated.
A study without flowers is not a house, and farmers without trees are not families.
Trees have no roots, and people have no ambition.
The old tree is half empty, and the old man is a knowledgeable person.
Thousands of feet never forgets his roots when he is tall, and never forgets his gratitude when he enjoys the scenery.
No bamboo is planted in front of the door, and no trees are planted behind the house.
The tree wants to keep quiet, but the wind will not stop; My son wants to serve his parents when they are old, but they are gone.
