Perhaps you should try some spelling variations:
yong yoon » wong yoon, yong khoon
yang yang » wang yang, wang yan
yuan ting » yuan ming, huang ting, yuan kang
ting yong » wang yong, tan yong, ting peng
yong yan » dong yang, ying yang, wang yan
lin zong » lin ling, lin meng
yi zong » yi rong

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((((yong yan) OR (yong yoon))) or (yang yang)) yuan ting yong ((yi zong) or (lin zong)) hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yong yan) OR (yong yoon))) OR (yang yang)) yuan ting yong ((yi zong) OR (lin zong)) hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yong yan) OR (yong yoon))) or (yang yang)) yuan ting yong ((yi zong) or (lin zong)) hai ;".
• Adding a wildcard symbol may retrieve word variants: wang ((((yong yan) OR (yong yoon))) or (yang yang)) yuan ting yong ((yi zong) or (lin zong)) hai ;*.
