Was Jia Baoyu with Qin Keqing or xiren for the first time? How old were they then?

Ke Qing can only be regarded as "psychosexuality", and what is really attacking people. I calculated Baoyu's age in this way: it is difficult to calculate his age from Daiyu's arrival in the mansion to the back. It is better to move him forward when he moves into the Grand View Garden, because the age of moving into the Grand View Garden is clear. At that time, he was twelve or thirteen years old, even if he was 13 years old. The Grand View Garden was built for one year, that is to say, Baoyu was 12 years old when he was a princess in Yuan Chun. After Ke Qing's death, Yuan Chun got a concubine at the beginning of the year. Ke Qing's death should be at the end of the year before Yuan Chun was given a concubine. When Ke Qing died, Yu Bao was 1 1 years old. It took about a year from Baoyu's sexual experience to Ke Qing's death. So when Baoyu tried his sexual experience, he was probably 10 years old. Back to the sixty-third "shroud red party banquet", xiren drew a lottery ticket and accompanied Geng people, as well as Xiangling, Qingwen and Baochai. It can be seen that xiren is the same age as Baochai and two years older than Baoyu, so xiren is 12 years old. -the above is my own inference, I don't know if it's right.
