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

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

• If you are trying to use Boolean operators, they must be ALL CAPS: min hyoung ((yihan guan) OR (yang guang)) ((tan yang) OR (tan ying)) mu dang hai ;~.
• Adding a wildcard symbol may retrieve word variants: min hyoung ((yihan guan) or (yang guang)) ((tan yang) or (tan ying)) mu dang hai ;*.
