yang jin » yang jie, ying jin, shang jin
yang jun » yang jui, pang jun, yang judy
long du » long d, long run, long did

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((dong yang) or (dong sin)) ya hua main ((yang jin) OR (yang jun)) ((long du) or (long do)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong yang) OR (dong sin)) ya hua main ((yang jin) OR (yang jun)) ((long du) OR (long do)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong yang) or (dong sin)) ya hua main ((yang jin) OR (yang jun)) ((long du) or (long do)) ;*".
