Hainan dialect "Do you know?" How to say sincerely ask authentic Hainanese solutions?

I am from Chengmai, Hainan, and I will answer you with Chengmai accent.

Mandarin translation in each language is not necessarily the number of words in the original text. "Do you know" can only be said in three words in Hainan dialect, that is, "Do you know?" Or "You know what?" Others wrote "Do you know?" Yes

In a word, these writing methods are for consistent pronunciation. Pinyin can be written as:

Lǔ deva?

(vǒ is sometimes pronounced as bǒ, how many people)
