Is there a description of Mulan Chai in the novel Walking on Thin Ice?

The description of Mulan's hairpin in the novel doesn't seem to be very prominent, but it has been strengthened in TV series. . .

Open the long and narrow wooden box in your hand, and it looks like a smooth suet Hosta. Carved into a blooming magnolia. This is the sentence when it first appeared. That's it. . .

Picked up the hair clasp and looked at it for a long time. Why does fourth brother like Mulan so much? "Mulan is embarrassed in the morning and embarrassed at night." "Drink Mulan dew early and eat autumn chrysanthemum late." Does he think he is as fragrant as Qu Yuan? Or do you feel that your ambition and talent can't be displayed?

I inserted the hair clasp carefully, studied it carefully, and couldn't help laughing, thinking that I couldn't use it anymore. I didn't expect it to be inserted in my head so soon.

When the May 4th Movement and the May 13th Movement came out, I greeted Ying Ying. Thirteen smiled and let me get up. The fourth brother stared at the hair clasp on my head, with a faint smile on his mouth, and then looked at me. I stood quietly with a smile on my lips, letting him look at me. Thirteen, look at us, we don't talk, we just stand by and watch.

Remember the first time Ruoxi saw Yongzheng holding a hair clasp in the palace? This is a passage. . .
