Perhaps you should try some spelling variations:
liang zhi » liang zhu, wang zhi, liang wei
gene sang » lee sang, gene bank
sang minh » kang minah, anh minh, song min
minh hong » minh cong, min hong, linh hoang
liang di » liang dan, liang wei, yang di
liang li » ling li, qiang li, liang wei
hua gene » human gene, a gene, hua ren
hong hai » shang hai, zhong tai, dang hai

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 di) OR (liang zhi))) OR (liang li)) hua gene sang minh hong hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((((liang di) or (liang zhi))) or (liang li)) hua gene sang minh hong hai ;*.
