Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
yihan guan » yan guan
thang long » change long
long span » long han
gene one » gene clone, gene gene, gene we
one gene » gene gene, one agent, e gene
man 11 » can 11, man 21

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: ((yang liang) OR (yihan guan)) man 11 ((gene one) OR (one gene)) thang long span ;~.
• Adding a wildcard symbol may retrieve word variants: ((yang liang) or (yihan guan)) man 11 ((gene one) or (one gene)) thang long span ;*.
