Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
qian yan » qian jun, qian yi
yan yang » yang yang, yao yang, dan yang
iii gene » iii rene, iii gender, iii genome
hong thi » hong ghi, phuong thi, zhong tai
hong hai » zhong tai, dang hai, hong tan
hong sau » wong sau, hong paul, kong sar
xi gene » i gene

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: qian yan yang ((xi gene) OR (iii gene)) ((hong thi) OR (((hong hai) OR (shang hai)))) hong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian yan yang ((xi gene) or (iii gene)) ((hong thi) or (((hong hai) OR (shang hai)))) hong sau ;~".
• Adding a wildcard symbol may retrieve word variants: qian yan yang ((xi gene) or (iii gene)) ((hong thi) or (((hong hai) OR (shang hai)))) hong sau ;*.
