Perhaps you should try some spelling variations:
chia wen » china won, ching wen, asia wen
yang jin » yang jie, yang jun, ying jin
wang lin » wang li, yang lin, wang limin
wang qin » wang qiao, wang jing, wang ning
zong hai » hong hai, dang hai, long han
yan tan » yan clan, yan guan, yan wang
tan tan » tas tan, tin tan, tang tang

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 tan) OR (tan tan)) chia wen ((((yang jin) OR (wang lin))) OR (wang qin)) zong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan tan) OR (tan tan)) chia wen ((((yang jin) or (wang lin))) or (wang qin)) zong hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan tan) OR (tan tan)) chia wen ((((yang jin) or (wang lin))) or (wang qin)) zong hai ;*.
