Perhaps you should try some spelling variations:
min hyoung » min hong, mun young
yang guang » yang yang, yang liang
yan guan » gan guan, yan yuan, yihan guan
tan yang » dan yang, tan yong, tao yang
tan ying » fan ying, ran ying, tan yong
dang » dan, lang, wang
hai » hadi, haji, hari

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

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