User:Mckrongs/Some MHOL confusion

So like, I need help. People that can help best are either those fluent in chinese, or those that play the game to know the information needed.

As you see here, there's X and Y. X is mostly used to represent the Monster in most MHOL-related websites, while Y only appears at the official page of the Monster. I was wondering what is X and what is Y? Is X the official Chinese Name? Or is X Chinese Titles? Or is Y the Chinese Name or the Chinese Title?
