Happy Year of the Tiger!
I don’t know if I explained this before, but every (solar) new year I send nengajō (new years’ cards) to my past Japanese teachers. It’s fun! Anyway, here’s mine from this year. It has a tiger and says “kinga shinnen”, which is a more formal “Happy New Year”.
Tomorrow I will ask my Vietnamese-speaking friends how to pronounce chúc mừng năm mới, since I can already do 新年快乐.
