A Dream of Red Mansions, episode 9 1: Baoyu and Daiyu meditate cross-legged to test each other's feelings, imitating Buddhism and expressing their love and loyalty in front language. Daiyu first asked, "Hello, Sister Bao. How are you? Sister Bao was good to you the day before yesterday, but now she is not good to you. How are you? Hello today, but not after. How are you? You are good to her, but she is not good to you. How are you? You are not good with her, and she is good with you. How are you? "
Baoyu thought for a long time and said with a smile, "I'll just take a ladle of water." Baoyu used this allusion to answer Daiyu's question, which means that Baochai's quality has nothing to do with me. Although there are many beautiful women in the world, you are the only one in my heart.
Daiyu was well aware of Baoyu's usual temperament and doubted whether he could keep his promise, so she continued to ask, "What can I do?" ; "What can I do to stop the pearl from sinking?" Baoyu said firmly, "Zen has been stained with mud, so I don't dance partridge spring breeze." My love for you is like a bird's nest made of flying catkins and mud, and it won't drift away with the wind again.

" The man replied, "Because of this, I don't know how to choose." The Buddha smiled and said, "Let me tell you a story. One day, a tourist was dying of thirst. The Buddha took pity on him and put a lake in front of him, but he didn't get a drop of water.
The Buddha was curious and asked why. Answer: there are many lakes, and the stomach is so small. Since you can't drink it all at once, you might as well not drink it at all. At this point, the Buddha smiled brightly and said to the unfortunate people, "remember, you may encounter many beautiful things in your life, but it is enough to grasp one of them with your heart." Weak water is 3,000, just take a scoop of water. "
