Translation:Father and Mother, good night!
Interesting question ! Let's start from scratch :-
Good morning = 早安 / 早上好
Good afternoon = 午安 / 下午好
Good evening = 傍晚 / 傍晚好 / 晚上好
Good night = 晚安 / xxxx = we don't use 晚上好 as Good night , sound so weird , c'mon ! Off to bed , sleep tight !
晚上好 = can be used in Good evening , which about 8-10pm
