Perhaps you should try some spelling variations:
gain yang » dan yang, daun yang, tan yang
wang wang » wang yang, wang liang, wang yan
shang hai » shang kai, dang hai, chang ha
hong hai » zhong tai, dang hai, hong tan
yang 4 » yang 47, yang _, yang 8
yan n » yan _, jan n
yan 4 » yan _, ban 4, man 4

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang wang ((yan n) or (((yan 4) OR (yang 4)))) gain yang di ((hong hai) or (shang hai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang wang ((yan n) OR (((yan 4) OR (yang 4)))) gain yang di ((hong hai) OR (shang hai)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang ((yan n) or (((yan 4) OR (yang 4)))) gain yang di ((hong hai) or (shang hai)) ;".
• Adding a wildcard symbol may retrieve word variants: wang wang ((yan n) or (((yan 4) OR (yang 4)))) gain yang di ((hong hai) or (shang hai)) ;*.
