对
duì
Using "dui" with verbs
对 points an action or attitude at someone — "towards", "to".
Subj. + 对 + Person + Verb
How it works
宝宝对我笑了 — the baby smiled at me. The 对 phrase goes before the verb.
It also introduces the thing an attitude is about: 我对中国文化很感兴趣 — I'm interested in Chinese culture.
对…来说 frames a perspective: 对我来说，这不难.
