What book did Baoyu read in A Dream of Red Mansions (2 1)?

Si Er was ordered to cut the candle and make tea. He read the South China Sutra again and went to the outer article "The Laundry", which read:

Therefore, abandoning wisdom and wisdom is a thief; A petty thief can't afford to destroy a pearl. Burning symbols break the seal, while the people are simple; Cutting barrels breaks the balance, and the people do not dispute; People can discuss the laws that violate the world's sacredness. If you disrupt the six methods, you will never hear the instrument, which will open your ears and make everyone in the world full of wisdom; Destroy the text, scatter the color, glue away from the eyes, and everyone in the world knows it; Destroy the hook rope and abandon the rules. The fingers of work hang down, and the beginning of the world contains its cleverness. Looking at this, I am full of interest, and I can't help but pick up the pen and continue: burning flowers and scattering musk deer, people in the boudoir have their words; Baochai's fairy posture and the spirit of grey Daiyu ruined love, and the beauty and evil of boudoir began to resemble each other. If he contains his suggestions, there is no danger of participating in the business; He has no love for his fairy posture; It is gray and has no talent. Hair, jade, flowers and musk deer all know their points, so they are confused by the world.
