Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
yan pang » yan wang, yang yang, yan liang
qian yan » qian jun, qian yi
pang ji » pang jiu, pan ji, yang jui
yan hui » yang hui, yuan hui, wang hui
hong ng » hong kong, hong jong, hong hong
wang » wing, 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 wan) yan pang ji qian yan hui ((shang hai) OR (hong ng)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang OR wan) yan pang ji qian yan hui ((shang hai) or (hong ng)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang OR wan) yan pang ji qian yan hui ((shang hai) or (hong ng)) ;*.
