Perhaps you should try some spelling variations:
yan yuan » yan guan, fang yuan, nan yan
chia dan » chia lan, chia wen
yang lin » yang jin, wang lin, yang li
zong hai » dang hai, long han, zong he
hong hai » shang hai, zhong tai, dang hai
shi dan » shi fan, shi ding, shi jian
wang » 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 OR wing) yan yuan ((chia dan) OR (shi dan)) yang lin ((zong hai) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) yan yuan ((chia dan) OR (shi dan)) yang lin ((zong hai) or (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wing) yan yuan ((chia dan) OR (shi dan)) yang lin ((zong hai) or (hong hai)) ;*.
