Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
young man » young men, young woman, young male
shang hai » dang hai, hong hai, zhang han
man xiao » yap xiao
chang ha » chang mae
yang du » yang di, yang d, yang jui
yang mu » yang muxi, yang jui, yang jun

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

• Performing a fuzzy search may retrieve terms with similar spellings: yang yang ((yang du) or (yang mu)) young man xiao ((((shang hai) OR (shang kai))) or (chang ha)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: yang yang ((yang du) OR (yang mu)) young man xiao ((((shang hai) OR (shang kai))) OR (chang ha)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang yang ((yang du) or (yang mu)) young man xiao ((((shang hai) OR (shang kai))) or (chang ha)) ;*".
