Barriers, barriers are walls, walls stand thousands of miles, and no desire is just. They want their relatives to be as tough as silk and as strong as walls.
"If you stand on a wall without desire, you will be strong, and the person you love will be as tough as silk and as strong as a wall." I hope the people I love hone themselves, and we must resolutely put an end to selfish desires in order to stand upright, stand like a mountain, and be tough and strong.
