Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
shang hai » shang kai, dang hai, chang ha
yang yao » wang yan, yang fan
hong hai » zhong tai, dang hai, hong tan
yang yi » yang xi, yang jui
n gain » _ gain, run gain
g yan » _ yan, g van, g yin
yan n » yan _, jan n, yan 4

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

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