Perhaps you should try some spelling variations:
ying chang » jin chang, yi chang, yin hang
yong yang » yang yang, dong yang, kyoung yang
ying yang » yang yang, yin yang, wang yang
iii gene » iii rene, iii gender, iii genome
ein kern » einem kern, ii kern
gene we » gene w, gene one, gene set
ghi » nghi, ghia

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((yong yang) or (((ying yang) OR (ying chang)))) iii gene we ((ein kern) or (im kern)) ghi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yong yang) OR (((ying yang) OR (ying chang)))) iii gene we ((ein kern) OR (im kern)) ghi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong yang) or (((ying yang) OR (ying chang)))) iii gene we ((ein kern) or (im kern)) ghi ;*".
