yang guang » yang yang, yan guan, yang liang
gan guan » yan guan, quan guan, fan guon
tan yang » dan yang, tan ying, tan yong
yang duc » yang du, sang duck, yang di
dang » dan, lang, wang

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wing hyoung) or (hwang byoung)) ((gan guan) or (yang guang)) tan yang duc dang (hai OR hadi) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wing hyoung) OR (hwang byoung)) ((gan guan) OR (yang guang)) tan yang duc dang (hai OR hadi) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing hyoung) or (hwang byoung)) ((gan guan) or (yang guang)) tan yang duc dang (hai OR hadi) ;*".
