Perhaps you should try some spelling variations:
gene clone » gene one
yang jing » wang jing, yang jin, huang jing
clone can » line can
yang jie » yang jin, yang di, yang jui
can only » can one
only sau » only a, only way, only see
m gene » _ gene, a gene, e gene

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wan ((yang jie) OR (yang jing)) m gene clone can only sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yang jie) OR (yang jing)) m gene clone can only sau ;*".
