Structure:

subject + 还是 + Action + (吧)

Meaning:

还是 as an adverb can express “had better” or “it would be better to”. The idea is that the speaker has given the matter some thought, and after considering it, has finally come to a decision. The announcement of this decision will frequently include 还是, and it usually comes before a verb or a subject.

Examples:

    你 不 会， 还是 我 做 吧。

    Nǐ bú huì, háishì wǒ zuò bɑ

    You can’t, I had better do it.
