Perhaps you should try some spelling variations:
a changed » _ changed, a change, has changed
shang kai » shang hai
iii gene » iii rene, iii gender, iii genome
yang jie » yang di, yang jui, yang xi
yang jin » yang jun, ying jin, shang jin
lang a » lang 3, lang _, erlang a
a gene » a genre, a gender, a gentle

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: lang a changed ((iii gene) OR (a gene)) ((yang jie) OR (yang jin)) shang kai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang a changed ((iii gene) or (a gene)) ((yang jie) OR (yang jin)) shang kai ;~".
• Adding a wildcard symbol may retrieve word variants: lang a changed ((iii gene) or (a gene)) ((yang jie) OR (yang jin)) shang kai ;*.
