Perhaps you should try some spelling variations:
yulan min » yuan ming
min jeong » kin keong, min hong, mun leong
jeong ghi » hong ghi, jeong mi
dong cao » dong xiao, dan cao, dong nan
dong bin » dong di, dann bin
a chen » ta chen, _ chen, z chen
n chen » _ chen, z chen, don chen
sin » sign, sind, skin

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((dong cao) or (((dong bin) or (dong sin)))) ya ((a chen) OR (n chen)) yulan min jeong ghi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong cao) OR (((dong bin) OR (dong sin)))) ya ((a chen) OR (n chen)) yulan min jeong ghi ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong cao) or (((dong bin) or (dong sin)))) ya ((a chen) OR (n chen)) yulan min jeong ghi ;".
• Adding a wildcard symbol may retrieve word variants: ((dong cao) or (((dong bin) or (dong sin)))) ya ((a chen) OR (n chen)) yulan min jeong ghi ;*.
