There is nothing wrong with it in northeast dialect, which means there is nothing wrong with it. When you meet some ridiculous people, things and things, you can ridicule them as "nothing wrong", which is actually wrong and problematic.

After hearing this, the boss said three words "nothing wrong" with a look of approval, which made people laugh. This word has become popular on the Internet. There is nothing wrong with it. At first, it probably means "no problem" in Northeast dialect, but with the continuous popularity, the definition of network is deeply rooted in people's hearts, which is completely contrary to the original definition. Because this word is full of skills, it often appears in the replies of major post forums, and even becomes the mantra of many people, and is widely used by everyone.
