How to say good night in Hakka dialect

The Hakka people would hardly use this sentence, because in ancient times the Hakka people were poor and would not use this sentence even when they went to bed after dark. You can use "shake up early to sleep" instead, that is, go to bed early and then go to sleep by yourself, which is almost the same as good night.

There is also a saying in Cantonese vernacular: trembling early, which means good night.
