gain yong » tan yong
yong jung » dong jung, hong jong, yang jun
zhong tai » hong tan, zhong zhi
chang ha » chang mae
hong hai » shang hai, dang hai, hong tan
a heat » a heart, _ heat, a head
yan a » can a, yan _, jan a
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 a heat gain yong jung ((chang ha) OR (((hong hai) OR (zhong tai)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan a heat gain yong jung ((chang ha) or (((hong hai) OR (zhong tai)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan a heat gain yong jung ((chang ha) or (((hong hai) OR (zhong tai)))) ;*.
