One of the experts in the video describes Wong Kim Ark as a “regular guy,” but also “unusual because he did something.” What does he mean by these two statements?

Hi. You didn't say which video this question refers to, which may leave my answer a little inaccurate, however, the expressions “regular guy,” and “unusual because he did something,” to describe the same person, it means that Wong Kim Ark did something out of the ordinary, but no one would suspect because he has a common appearance that makes him not stand out from the crowd.

Explanation:

The characteristics of Wong Kim Ark mentioned in the question above probably refer to the duality between his appearance and the actions he performs. When the text states that he was “unusual because he did something" the text shows that he does things that are not common or even normal in society, they are special actions. However, the text also says that he is a “regular guy, ”Which shows that they had a common appearance that allowed him to blend into the crowd and not be noticed.
