Perhaps you should try some spelling variations:
yan yuan » fang yuan, nan yan, yan clan
yan guan » gan guan, yang guang, yihan guan
yang jun » pang jun, yang jin, yang judy
yong jui » yong cai, yong suk
yang jui » yang judy, yang di, yang xi
dan hai » dang hai, dan phan, dann hat
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 hyoung ((((yan yuan) or (yan guan))) or (yang jun)) tan ((yong jui) OR (yang jui)) dan hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang hyoung ((((yan yuan) OR (yan guan))) OR (yang jun)) tan ((yong jui) OR (yang jui)) dan hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang hyoung ((((yan yuan) or (yan guan))) or (yang jun)) tan ((yong jui) OR (yang jui)) dan hai ;*".
