Perhaps you should try some spelling variations:
yang guang » yang yang, yang liang
yan guan » gan guan, yihan guan, quan guan
yan yuan » fang yuan, nan yan, yan clan
yang duc » sang duck, yang di, yang jui
yang du » yang di, yang d, yang mu
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 guan) OR (yan yuan))) or (yang guang)) tan ((yang duc) or (yang du)) dan hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang hyoung ((((yan guan) OR (yan yuan))) OR (yang guang)) tan ((yang duc) OR (yang du)) dan hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang hyoung ((((yan guan) OR (yan yuan))) or (yang guang)) tan ((yang duc) or (yang du)) dan hai ;*".
