Perhaps you should try some spelling variations:
a changed » _ changed, a change, has changed
iea genre » de genre, le genre, new genre
zhang hai » zhang dai, shang hai, zhang han
li zhang » _ zhang
a genre » _ genre, a gender, a gentle
yang li » yang lin, yang di, yang xi
lang a » lang 3, lang _, erlang a

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 ((iea genre) OR (a genre)) yang li zhang hai ;~.
• Adding a wildcard symbol may retrieve word variants: lang a changed ((iea genre) or (a genre)) yang li zhang hai ;*.
