Perhaps you should try some spelling variations:
kang young » wang hyoung
yang juan » yang jun, huang juan, jiang juan
yan plan » yan clan, can plant, plan plan
juan ke » juan de, juan e, juan die
long du » long d, long run, long did
long do » long d, longer do, long ago
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) OR (kang young)) yang juan ke yan plan ((long du) OR (long do)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (kang young)) yang juan ke yan plan ((long du) OR (long do)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) or (kang young)) yang juan ke yan plan ((long du) OR (long do)) ;*.
