Perhaps you should try some spelling variations:
lang yan » wang yan, wang yang, zhang yan
liu gang » liu gangs, liu yang, li gang
gang min » gong min, tang min, chang min
min long » min hong, pain long, min jeong
yuan zi » yuan li, yuan fei, yuan hui
yang xi » yang di, yang yi, yang jui
long du » long d, long do, long run
yan zi » yan zhi, 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: lang yan ((((yuan zi) OR (yan zi))) OR (yang xi)) liu gang min long du ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((((yuan zi) OR (yan zi))) or (yang xi)) liu gang min long du ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((((yuan zi) OR (yan zi))) or (yang xi)) liu gang min long du ;*.
