Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
zwang zum » zwang zur, zugang zum
yan guan » gan guan, yan yuan, yang guang
yang yun » yang jun, tang yun, yang yue
yang zum » gang zum, drang zum, yang jui
gang hai » dang hai, shang hai, eang hay
yan kun » yan yuan

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 yong ((((yan kun) OR (yan guan))) OR (yang yun)) gain ((yang zum) OR (zwang zum)) gang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((((yan kun) or (yan guan))) or (yang yun)) gain ((yang zum) OR (zwang zum)) gang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ((((yan kun) or (yan guan))) or (yang yun)) gain ((yang zum) OR (zwang zum)) gang hai ;*.
