Perhaps you should try some spelling variations:
qian wang » yiqian wang, qian rong, qian yan
yan wang » yuan wang, yang yang, yan liang
chan eng » chan fong, chan kang, chan ming
hong lan » huong lan, hong tan, hong gang
chang 2 » chang _, anhang 2, chang ha
chang c » chang _, anhang c, chang ha
yang i » yang di, yang xi, yang yi
i gene » _ gene, a gene, e gene

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: ((((yan wang) OR (qian wang))) OR (chan eng)) yang i gene ((chang 2) OR (chang c)) hong lan ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yan wang) OR (qian wang))) or (chan eng)) yang i gene ((chang 2) or (chang c)) hong lan ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yan wang) OR (qian wang))) or (chan eng)) yang i gene ((chang 2) or (chang c)) hong lan ;*.
