I was curious about the Wei Tang Brothers ' seemingly dual-component surname, and looked into the trivia section to see if there's any mention of official clarification on the subject. Turns out there was, but following the cited link , I discovered that there's a huge misunderstanding, as the statement says that "Wei" the full surname while "Tang" is just a shared component of the brothers' respective given names (which is common in naming of real-life Chinese siblings), yet the relevant trivia entry says that "Tang" is a component to the family name "Wei", and the lead section of the article mirrors that.
I'll be correcting this error right after posting this; I'm just posting this to provide a clear explanation for this relatively non-trivial edit.
