In the 24th episode of A Dream of Red Mansions, Jia Yun is in Baoyu's study. Xiaohong calls "Brother" outside. Who is Xiaohong's brother?

This girl's name is Xiaohong, 16 years old. Her real name is Lin and her nickname is Redjade. Because of the word "jade", she is called "Xiaohong". She is an old servant of the Guo Rong family for generations, and her parents are now in charge of real estate affairs everywhere. She is a talkative, intelligent and high-minded girl who is bent on going up.

Who is Xiaohong calling? There is no clear description in the article, but in my personal opinion, her name should be Jia Yun. The article said, "Jia Yun looks at calligraphy and antiques" and "only listens to the delicate voice in front of the door and calls out' brother'. Jia Yun looked out and saw a girl of 16 or 17, who was also handsome and clean. When the girl saw Jia Yun, she pulled away and hid. " It can be seen that when Jia Yun looked out, Xiaohong saw him. If he hadn't called him, how could he have seen him the first time? I restored the scene: Jia Yun was reading calligraphy and painting, and Xiaohong saw it in front of the door. Because she was far away, she didn't see her face. She thought it was from her family and called her brother. But when Jia Yun turned around, he found that he looked strange and thought he was a foreign man, so he pulled away and hid.

There is a third person in this joke, baking tea. But then he came out. Moreover, "when I was baking tea, I saw the maid at the door and said,' OK, OK, I can't hear the news.' ""after waiting for this day, no one has come yet. " "This shows that little red is not calling him. Baking tea is just behind "Brother", which they didn't see before.

My humble opinion, please advise.
