Jia Baoyu has four questions about Lin Daiyu: reading, names, words and jade. Why did he put "ask jade" at the end?

Tip: Baoyu is "stupid and afraid of reading articles" He is most afraid of reading Confucian classics such as the Four Books and Five Classics and Zhu Zi's Notes, but he likes excellent literary books, such as The West Chamber and The Peony Pavilion. When he first met Daiyu, he wanted to know if Daiyu could read, what books she liked to read and whether she had similar interests. Turning to asking for names and words not only conforms to the custom of people's first communication, but also reflects Baoyu's consciousness of equality between men and women (ancient women were generally nameless and speechless). Because Daiyu has "jade" in her name, she also has "jade" in her own name and wears jade around her neck, so it is natural to ask jade. This is also the author's careful arrangement, because it triggered the plot of "falling jade" and highlighted Baoyu's rebellious character.
