Perhaps you should try some spelling variations:
yan yang » yang yang, dan yang, tan yang
yao yang » yang yang
song kin » song min, song shin, song bing
song jin » song min, shang jin, song shin
jeong su » jeong _, jeong 情, rong su
jeong mi » jeong _, jeong 情, jong min
xi l » xu l, i l, xi _
wang » wing, wan, lang

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: wang ((yan yang) OR (yao yang)) xi l ((song kin) OR (song jin)) ((jeong su) OR (jeong mi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yang) or (yao yang)) xi l ((song kin) or (song jin)) ((jeong su) OR (jeong mi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yang) or (yao yang)) xi l ((song kin) or (song jin)) ((jeong su) OR (jeong mi)) ;*.
