Is the "vào" necessary here?
In Vietnamese language "next year" also mean "sang năm"
do you need to use 'sẽ' in this sentence since it is clear from the context that you are talking about the future?
True but we want to be consistent.
Is the comma here necessary?
I thought 'tìm thấy' was find, and 'tìm' was 'look for' or search.
Isn't there also a 'năm ngoài'?
I recall a sentence: My family will go to France next year" using 'năm ngoài' instead of "sau" or tới.
The preferred verb, 'tìm', is not in the hints.
