Perhaps you should try some spelling variations:
liang yang » wang yang, yang yang, huang yang
liang ying » liang liying, huang ying, zhang ying
han chang » huang chang, than change, can change
chang won » chang soon, chang ann, chang min
hong hai » shang hai, zhong tai, dang hai
hong yu » wong yue
xi han » ti han, xi zhang

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

• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((liang yang) OR (liang ying)) xi han chang won ((hong hai) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((liang yang) OR (liang ying)) xi han chang won ((hong hai) or (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((liang yang) OR (liang ying)) xi han chang won ((hong hai) or (hong yu)) ;*.
