Perhaps you should try some spelling variations:
hyoung hoang » kyoung yang, dong hoang, young young
shang hai » shang kai, dang hai, chang ha
hoang sy » hoang vu
yang lin » wang lin, yang liang, huang lin
yang jin » yang jie, yang jun, ying jin
wong yue » wang yue, hong yu
yang li » yang di, yang xi, yang yi
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 hyoung hoang sy ((((yang lin) OR (yang jin))) OR (yang li)) yi ((shang hai) OR (wong yue)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang hyoung hoang sy ((((yang lin) OR (yang jin))) or (yang li)) yi ((shang hai) or (wong yue)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang hyoung hoang sy ((((yang lin) OR (yang jin))) or (yang li)) yi ((shang hai) or (wong yue)) ;*.
