Liu agrees that he is a nobleman, but his prototype is the daughter of an abandoned prince, which is far-fetched. In the whole Dream of Red Mansions, the image of Qin Keqing is a bit mysterious, but as long as we grasp the key point that Qin Keqing is a fairy, then all mysteries can be solved. Many characters in A Dream of Red Mansions are immortals. For example, a monk and a police fairy are typical immortals. Jia Baoyu and Lin Daiyu belong to Shen Ying waiter and crimson pearl fairy. What about Qin Keqing? The fifth dreamland in the book clearly shows that Qin Keqing, whose real name is Ke Qing, is the sister of the police fairy, not only a fairy, but also an extraordinary position. Immortals are often described as mortals, but they all have the characteristics of immortals more or less. For example, Jia Baoyu loves to be close to her daughter, because the waiter in Shen Ying is a gardener, and Lin Daiyu loves to cry, because the crimson pearl fairy wants to repay her tears. Both of them are extraordinary and lack the heart of fame and fortune, because the immortals are empty and represent truth, goodness and beauty. In his book, Qin Keqing is such a seemingly mortal but immortal person. She is an abandoned baby brought by Yangshengtang, because she is a fairy and her natural origin is unknown. She is graceful, gentle and peaceful, which is the first pride of the daughter-in-law of great-grandson, because she is the sister of the police fairy, taller than the crimson pearl fairy and natural. After her death, she used a wooden coffin, and the funeral was extremely luxurious, which also hinted at her noble position in the celestial world. The fifth time, there was an exaggerated description of the furnishings of the home, which was thought to imply lewdness before, while Liu thought it implied nobility. I agree with Liu. It means nobility. Only fairies with noble status will have such furnishings. There is an obvious sentence in the article. Qin said with a smile, "I can live in a fairy in this room." This strongly suggests that Qin Keqing is a fairy. In A Dream of Red Mansions, Qin Keqing touched Jia Fu twice, once touched Jia Baoyu in his dream and once touched Wang Xifeng in his dream. Since then, Qin Keqing died early and returned to the celestial world. This is somewhat similar to The Journey to the West's writing. Guanyin, entrusted by the Tathagata, became an old monk to enlighten the Tang King and Tang Priest to learn from the Western Heaven, and then flew away. The magic fairy is similar to Buddha, and Qin Keqing is similar to Guanyin. The design of these two words is to play a role in threading the needle and outlining the outline. In a word, Qin Keqing is a fairy, and it is meaningful for all puzzles to understand this. Liu realized the mysterious and noble characteristics of the prince, but it was not because the fairy came down to earth, but because the abandoned prince's daughter was unconvincing because of the lack of clear evidence and logical reasoning.
