Perhaps you should try some spelling variations:
song byung » song bing, song yun, sung myung
hyoung shi » layoung shin
yang yang » wang yang, wang yan
yan yang » yao yang, dan yang, tan yang
song jin » song min, shang jin, song shin
yi ai » yi dai, yi lai, i ai
ai ai » ai a, ii ai, vi ai

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan ((yan yang) or (yang yang)) ((yi ai) OR (ai ai)) ((song jin) or (song byung)) hyoung shi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((yan yang) OR (yang yang)) ((yi ai) OR (ai ai)) ((song jin) OR (song byung)) hyoung shi ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yan yang) or (yang yang)) ((yi ai) OR (ai ai)) ((song jin) or (song byung)) hyoung shi ;".
• Adding a wildcard symbol may retrieve word variants: wan ((yan yang) or (yang yang)) ((yi ai) OR (ai ai)) ((song jin) or (song byung)) hyoung shi ;*.
