Here are some things you can try to find the correct name:
* Check for spelling variations: Is it possibly "Mo Ming," "Moy Min," or something similar?
* Look for additional information: Do you remember anything else about the actor, like their role in the project, the genre of the movie or TV show, or the approximate year it was released?
* Use a movie database: Websites like IMDb (Internet Movie Database) or TMDb (The Movie Database) are excellent resources for finding information about actors, movies, and TV shows. Try searching for the project itself and see if you can find the actor in the credits.
