Perhaps you should try some spelling variations:
yihan guan » yan guan
yan yuan » yan guan, fang yuan, nan yan
yang jun » pang jun, yang jin, yang judy
yong jui » yong cai, yong suk
yang jui » yang judy, yang di, yang xi
gang hai » dang hai, shang hai, eang hay
wang » wing, wan, lang

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang yan ((((yan yuan) or (yihan guan))) or (yang jun)) tan ((yong jui) OR (yang jui)) gang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan ((((yan yuan) OR (yihan guan))) OR (yang jun)) tan ((yong jui) OR (yang jui)) gang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((((yan yuan) or (yihan guan))) or (yang jun)) tan ((yong jui) OR (yang jui)) gang hai ;*".
