Zhou Libo's sentence ... Is the hairstyle clear? Is it Shanghainese? What do you mean?

The original words are: Aladou clears the throat

The original meaning is: Is my hairstyle clean? Is the grain of my hair clear?

As "Dousi" in Shanghainese can be translated into "hairstyle" and "hair lines", it can also be understood as "mind" and "thinking", so the extension of this sentence means: Is my thinking clear? That is, Zhou Libo explained to the audience that he has a clear mind and quick thinking.
