Perhaps you should try some spelling variations:
lang yanling » wang yanling, wang yangming, zhang yunling
min jeong » kin keong, min hong, mun leong
yang li » yang lin, yang di, yang xi
yi gang » ii gang, li gang, yi yang
jeong d » jeong _, jeong 情, jeong mi
yan li » yuan li, gan li, tan li
i gang » ii gang, li gang, 2 gang

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: lang yanling ((yan li) OR (yang li)) ((i gang) OR (yi gang)) min jeong d ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yanling ((yan li) or (yang li)) ((i gang) OR (yi gang)) min jeong d ;~".
• Adding a wildcard symbol may retrieve word variants: lang yanling ((yan li) or (yang li)) ((i gang) OR (yi gang)) min jeong d ;*.
