In the novel "Dream of the Red Chamber", Jia Baoyu's favorite is Lin Daiyu, he is not Lin Daiyu, even if he marries the dignified and beautiful and gentle and virtuous Xue Baochao, he still remembers Lin Daiyu, and finally he sees through the red dust and becomes a monk.
Jia Baoyu and Lin Daiyu are truly in love with each other, but the love between him and Lin Daiyu is pure, not even a hug or a kiss. However, Jia Baoyu and a person were not pure before marriage, and this person was an attacker.

Jia Baoyu had a soft dream on the bed of his niece-in-law Qin Keqing, dreaming that the police fairy goddess had given him her beautiful sister Ke'er Xu and went to Wushan Yunyu together. After waking up, the youth and desire in Jia Baoyu's body suddenly sprouted, he told this dream in detail to the attacker, the attacker smiled shyly, and then Jia Baoyu asked and the attacker to try the dream, and the attacker also agreed.
So Jia Baoyu and the young boy and girl who attacked the people tried yun and rain for the first time, fortunately, the attackers were too young and not pregnant, otherwise they would make a big joke.
Jia Baoyu seemed to separate love from his body, and he didn't feel sorry for Lin Daiyu. The first attempt at Yun Yu was a youthful initiation of his life, and he had never had such a physical communication with the raider since then.
Jia Baoyu and the raiders first tried yun and rain, did Lin Daiyu know? Lin Daiyu has always liked to fight for the wind and be jealous, jia Baoyu is better to whom, Lin Daiyu is suspicious in her heart. In particular, the legend of the golden jade good relationship made Lin Daiyu always suspect that Jia Baoyu would fall in love with Xue Baochao, or marry Xue Baochao.
Lin Daiyu once jokingly called the attacker's sister-in-law, but that was only because Madame Wang raised the monthly money of the raider to the level of a concubine, and all the treatment that Aunt Zhao and Aunt Zhou had, the raiders had to have. Everyone in Rong Guo Mansion knew that raiders would become Jia Baoyu's concubines in the future, and Lin Daiyu certainly knew it, so she would jokingly call raiders sister-in-law.
Raiders and Jia Baoyu had tried Yun Yu for the first time, and Qingwen might know. But Lin Daiyu wouldn't know. The attacker behaved unruly in front of Lin Daiyu, and Lin Daiyu couldn't see what Jia Baoyu looked like with the attackers on a daily basis.
For an aristocratic girl, even reading love novels like Xi Xiang Ji is regarded as a bad behavior, how could Lin Daiyu think that Jia Baoyu would have a cloud and rain affair with the attacker?
Raider is also a very strange person, she and Jia Baoyu have tried yunyu for the first time, but proposed to Madame Wang that Jia Baoyu move out of the Grand View Garden and not mix with her sisters and sisters. Isn't this just a matter of allowing state officials to set fires and not allowing the people to light lamps? Strict with the law, lenient with the self.
Lin Daiyu definitely did not know that Jia Baoyu and the raider had a physical intimate relationship when they first tried Yun Yu.
