Perhaps you should try some spelling variations:
yan hoang » tran hoang, tan hong, anh hoang
shang hai » shang kai, dang hai, chang ha
hoang yi » hoang vu, yang yi, hoang sy
yi huang » fei huang, 16 huang, d huang
hong hai » zhong tai, dang hai, hong tan
wong yue » wang yue, hong yu
ting li » tang li, liang li, qiang li
wang » wing, wan, lang

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 yan hoang yi huang ((ting li) OR (ling li)) ((((hong hai) OR (shang hai))) OR (wong yue)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan hoang yi huang ((ting li) or (ling li)) ((((hong hai) OR (shang hai))) or (wong yue)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan hoang yi huang ((ting li) or (ling li)) ((((hong hai) OR (shang hai))) or (wong yue)) ;*.
