Perhaps you should try some spelling variations:
qian dan » qian yan, liang dan, qian wang
dan yang » daun yang, tan yang, wang yang
hong thi » hong ghi, phuong thi, zhong tai
hong hai » shang hai, zhong tai, dang hai
hong sau » wong sau, hong paul, kong sar
yang xi » yang di, yang yi, yang jui
xi gene » i gene, iii 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 dan yang xi gene ((hong thi) OR (hong hai)) hong sau ;~.
• Adding a wildcard symbol may retrieve word variants: qian dan yang xi gene ((hong thi) or (hong hai)) hong sau ;*.
