Perhaps you should try some spelling variations:
yue cheng » yu cheng, yuan cheng, ke cheng
yang july » yang judy, yang jui, yang jun
shang hai » shang kai, dang hai, chang ha
tan ying » fan ying, tan yang, tan yong
ran ying » fan ying, jin ying, gao ying
wang yue » wong yue, wang hua, wang yan
yang jin » yang jie, yang jun, ying jin

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tan ying) OR (ran ying)) wang yue cheng ((((yang di) or (yang jin))) or (yang july)) shang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tan ying) OR (ran ying)) wang yue cheng ((((yang di) OR (yang jin))) OR (yang july)) shang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tan ying) OR (ran ying)) wang yue cheng ((((yang di) or (yang jin))) or (yang july)) shang hai ;*".
