Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
quan guan » gan guan, quan guo, yan guan
dang hari » dang hai
gun guan » gan guan, gui guan, tuo guan
fan yang » dan yang, fan ying, tan yang
yang mu » yang du, yang muxi, yang jui
mu dang » duc dang

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

• Performing a fuzzy search may retrieve terms with similar spellings: lang hyoung ((gun guan) OR (quan guan)) fan yang mu dang hari ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang hyoung ((gun guan) OR (quan guan)) fan yang mu dang hari ;*".
