Why do Henan women only like to pick their nostrils?

My friend, the question you asked contains disrespect for the female compatriots in Henan! Is picking one's nose a "patent" for Henan people? Isn't this interesting? I'm not from Henan, and I often pick my nose. You never pick your nose? Joke! When nosebleeds accumulate in the nostrils, they will pick their noses and pick their nosebleeds, no matter at home or abroad, everyone does! Of course, picking your nose in front of everyone is indecent and should be avoided. It's a matter of politeness in personal appearance and behavior. Don't blame Henan women. This is a very inappropriate view.
