Perhaps you should try some spelling variations:
gene sang » lee sang, gene bank
tin zhong » tin hong, bin zhang, ji zhong
zhong zhi » zhang zhi, hong ghi, zhong tai
yang hua » wang hua, yang hui, ying hua
yang jun » yang jui, pang jun, yang jin
wang hui » wang hua, wang zhi, wang wei
sang tin » sang minh, lang tim, sang tae

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 yanling ((((yang hua) OR (yang jun))) OR (wang hui)) gene sang tin zhong zhi ;~.
• Adding a wildcard symbol may retrieve word variants: wang yanling ((((yang hua) or (yang jun))) or (wang hui)) gene sang tin zhong zhi ;*.
