chang min » zhang ming, chang mae, chan ming
huang lin » huang bin, huang jing, huang ting
hua gene » human gene, a gene, hua ren
tang min » sang minh, yang mind, tang li
hong shu » cong shu, tong shui, wong shiu
jing ji » ying jin
ala » alan, alam, alia

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: long hoang ala hua gene ((((tang min) OR (chang min))) OR (((huang lin) OR (jing ji)))) hong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "long hoang ala hua gene ((((tang min) OR (chang min))) or (((huang lin) or (jing ji)))) hong shu ;~".
• Adding a wildcard symbol may retrieve word variants: long hoang ala hua gene ((((tang min) OR (chang min))) or (((huang lin) or (jing ji)))) hong shu ;*.
