Perhaps you should try some spelling variations:
wang liang » wang yang
yang cindy » yang mind
liang yi » jiang yi, liang li, liang ying
hua gene » human gene, a gene, hua ren
yang min » yang mind, tang min, yang lin
yang jin » yang jie, yang jun, ying jin
hong ghi » zhong zhi, hong g
hong hai » shang hai, zhong tai, dang hai
yi hua » li hua, ya hua, yi hui

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: wang liang yi hua gene ((((yang min) OR (yang cindy))) OR (yang jin)) ((hong ghi) OR (hong hai)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang liang yi hua gene ((((yang min) or (yang cindy))) or (yang jin)) ((hong ghi) or (hong hai)) ;*.
