Perhaps you should try some spelling variations:
changes made » changes a, changes due
yi chang » ii chang, ying chang, jin chang
yu cheng » _ cheng
yang jie » yang di, yang jui, yang xi
yang jin » yang jun, ying jin, shang jin
yu chen » yi chen, yulu chen, jui chen
yang yi » yang di, yang xi, yang jui
fan yi » tan yi, fan ying

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "fan yi chang ((yu chen) OR (yu cheng)) ((((yang jie) OR (yang jin))) OR (yang yi)) changes made ;~".
• Adding a wildcard symbol may retrieve word variants: fan yi chang ((yu chen) OR (yu cheng)) ((((yang jie) OR (yang jin))) OR (yang yi)) changes made ;*.
