Perhaps you should try some spelling variations:
shang hai » shang kai, chang ha, hong hai
ran ying » fan ying, jin ying, gao ying
tan ying » fan ying, tan yang, tan yong
yang hua » wang hua, yang hui, ying hua
hua chen » jui chen, yu chen, a chen
yang lin » yang jin, wang lin, yang li
yang xi » yang di, yang yi, yang jui

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((ran ying) OR (tan ying)) yang hua chen ((yang lin) or (yang xi)) ((shang hai) or (dang hai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ran ying) OR (tan ying)) yang hua chen ((yang lin) OR (yang xi)) ((shang hai) OR (dang hai)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ran ying) OR (tan ying)) yang hua chen ((yang lin) or (yang xi)) ((shang hai) or (dang hai)) ;".
• Adding a wildcard symbol may retrieve word variants: ((ran ying) OR (tan ying)) yang hua chen ((yang lin) or (yang xi)) ((shang hai) or (dang hai)) ;*.
