I'm trying to learn the few remaining HSK5 words I haven't fully learned yet. This one I keep forgetting:
周到 (zhōudào / zhōudao)
CC-CEDICT: thoughtful / considerate / attentive / thorough
It would help to understand the underlying logic here, but I can't figure it out: 周到 seems like the combinations of two random characters.
CC-CEDICT: to make a circuit / to circle / circle / circumference / lap / cycle / complete / all / all over / thorough / to help financially
CC-CEDICT: to (a place) / until (a time) / up to / to go / to arrive / (verb complement denoting completion or result of an action)
I get nothing from this, and googling
周到 etymology didn't give anything useful.
Question: How does 周到 mean "thoughtful"?
