Something local? Like we have these "salt candies" at Finland. Some are sweet, some are not. I brought some to be tasted. She liked the sweet ones, though it tasted strange in her opinion haha...
Also I brought my grandmothers home made wool socks for her (which I have like 100 pairs since she always used to make wool socks...). And she said that they do not have wool socks at China, or at least in that city. And she really loved the socks, because it can get cold during the winter.
But medicine and vitamins. On my trip, I brought some normal pain/fever medication. Which also cures hangover, flu, muscle pain, its cheap and sold without a prescription in the pharmacy. So I gave the spare ones after my journey was over, and all kinds of other medication which I brought "just in case" so I would not have to visit the Chinese hospital if I got sick... Which the local pharmacy sells without prescriptions. As example lactic acid pills, which helps the stomach to digest.
Oh and sun scream. Because they do not like the sun... And I actually bought it for myself but I gave it to her.
