"Si Qin's hair is falling out badly after having a baby, take this with you. Last time I saw her, her skin looked a bit sallow, take this too. Cubilose and donkey-hide gelatin are all-purpose, bring them along."
Zheng Siqing is Zheng Da's daughter, and Zheng Siyuan's sister. Qin Huai had never met her but had heard Zheng Siyuan mention that his sister is socially anxious and doesn't like going out. Her skin got worse after having a baby, and her hair was falling out heavily, which made her even more reluctant to leave the house. She stays at home every day pondering how to grow her hair back.
Watching the Gong family choose gifts to bring, Qin Huai thought he should record this scene and send it to Huang An Yao to study and learn from.
Look, this is what precise gift-giving looks like.
Bringing two bags of fruit as gifts is just too ordinary, and that's not to mention forgetting to buy cherries.
