Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
dong sink » dong sin, dong bin, dong ping
chang min » zhang ming, chan ming, chang ann
chang mae » chang ha, changes made
jeong shu » jeong su, cong shu
hua rest » hua ren
han min » han men, kan min, chan ming

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang yang) or (dong sink)) ya hua rest ((han min) or (((chang min) OR (chang mae)))) jeong shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (dong sink)) ya hua rest ((han min) OR (((chang min) OR (chang mae)))) jeong shu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (dong sink)) ya hua rest ((han min) or (((chang min) OR (chang mae)))) jeong shu ;".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (dong sink)) ya hua rest ((han min) or (((chang min) OR (chang mae)))) jeong shu ;*.
