yang yang » wang yang, wang yan
kong saur » kong sar, kong siu, kong your
yin yang » yi yang, yin fang, yin hang
hua gene » human gene, a gene, hua ren
ying tan » wing tan, liang tan, ying bank
yang jin » yang jie, yang jun, ying jin

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

• Performing a fuzzy search may retrieve terms with similar spellings: ran ((((ying yang) OR (yin yang))) or (yang yang)) hua gene ((ying tan) or (yang jin)) kong saur ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ran ((((ying yang) OR (yin yang))) OR (yang yang)) hua gene ((ying tan) OR (yang jin)) kong saur ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ran ((((ying yang) OR (yin yang))) or (yang yang)) hua gene ((ying tan) or (yang jin)) kong saur ;".
• Adding a wildcard symbol may retrieve word variants: ran ((((ying yang) OR (yin yang))) or (yang yang)) hua gene ((ying tan) or (yang jin)) kong saur ;*.
