Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
yang xi » yang yi, yang jui
hong ng » hong jong, hong hong
yan yi » yang yi, tan yi, yan zi
i gene » _ gene, a gene, e gene
yi i » yi ki, i i, ii i
wang » wing, wan, lang
kong » long, pong, ong

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

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