Translation:I'll see my girlfriend next year.
If someone told me they were going to see their girlfriend, i would assume they ment in person.
It's either Duo's translation, or just being extremely specific for clarity.
Why can't you use the word 'can' as it is a perfectly good translation for hui 会
Like I CAN 会 see my girlfriend next year, rather than WILL SEE. Isn't this more accurate?
I think If you wanted to use can, u must use 可以 most likely, because 会 is really just the tense that you need to put the sentence into the future tense.
