I was trying to post new question:
Can we use Kanji for 「びっくりした」 (surprised)?
Can we use Kanji for 「びっくりした」(surprised) like 「吃驚した」? If so, is it recommended?
And the system didn't allowed to do it, saying this is a duplicate of this question..
But my question is absolutely not a duplicate. Maybe this is a system error?
