The most plausible explanation is as per the last part of this video.
All the brothers had the same middle character in their names as per correct Chinese tradition - Runme, Runrun, Runje, etc
Not like some half baked AhLeeBaba, I wouldn't even consider them Chinese if their gambling and fumbling papa couldn't even get the naming convention right and used the last character as the common one instead. Really no eye see. Kuanyew, Suanyew, Thankyew, etc. Might as well make it Suakoo, Tankoo, Teekoo, Kookoo, etc.
