Perhaps you should try some spelling variations:
chung wang » chung kang, chen wang, chong wan
china wang » china yang, china chang, china zhang
tang tang » taizong tang
chen yang » chen rong
yang yi » yang di, yang xi, yang jui
hong yu » wong yue
yan zi » yan zhi, yuan zi, ban zi

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: tang tang ((yan zi) OR (yang yi)) chen ((((chung wang) OR (china wang))) OR (chen yang)) hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tang tang ((yan zi) or (yang yi)) chen ((((chung wang) OR (china wang))) or (chen yang)) hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: tang tang ((yan zi) or (yang yi)) chen ((((chung wang) OR (china wang))) or (chen yang)) hong yu ;*.
