Perhaps you should try some spelling variations:
planning can » planning chain, planning case, planning land
danning can » banking can, winning can, learning can
yang yang » wang yang, wang yan
kim shang » kim song, kim ching, kim jang
shang hai » shang kai, dang hai, chang ha
tan ying » fan ying, ran ying, tan yang

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 ((danning can) OR (planning can)) china ((tan ying) OR (yang yang)) kim shang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((danning can) OR (planning can)) china ((tan ying) or (yang yang)) kim shang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((danning can) OR (planning can)) china ((tan ying) or (yang yang)) kim shang hai ;*.
