https://news.ycombinator.com/item?id=13947061I was on a trip to Malaysia recently and met many native Chinese speakers who reply "Can" when you ask them something like "Can you meet me at 5 tomorrow?". I asked him why they don't say "Yes" and he said that in Chinese, that would sound really silly.
I imagine it's similar to writing "Sword of so and so" on a weapon rather than just writing ones name. In some languages, it's more... regal.
