Perhaps you should try some spelling variations:
changes made » changes a, changes due
liang using » liang ying, yang using, change using
wang liang » wang yang
made hong » trade hong, ma hong, care hong
a schenk » r schenk, a schema
a scene » la scene, _ scene, a science
tan » than

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: wang liang using ((a schenk) OR (a scene)) changes made hong tan ;~.
• Adding a wildcard symbol may retrieve word variants: wang liang using ((a schenk) or (a scene)) changes made hong tan ;*.
