Perhaps you should try some spelling variations:
yang xiang » yang liang, wang liang, yan liang
yang yang » wang yang, wang yan
minh song » minh cong, jin song, min hong
song sein » song shin, song jin, song min
yang jui » yang judy, yang di, yang yi
wan yan » wang yan, nan yan, wai yan
yang xi » yang di, yang yi

You may be able to get more results by adjusting your search query.
