Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
yin yang » ying yang, yi yang, yin fang
wei chen » wei shen, jui chen, yi chen
yang jie » yang di, yang jui, yang xi
yang jin » yang jun, ying jin, shang jin
wan yin » fan ying, ran ying, tan ying
yang yi » yang di, yang xi, 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: wan yin yang ((wei chen) or (frei chen)) ((((yang jie) OR (yang jin))) or (yang yi)) shang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan yin yang ((wei chen) OR (frei chen)) ((((yang jie) OR (yang jin))) OR (yang yi)) shang hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yin yang ((wei chen) or (frei chen)) ((((yang jie) OR (yang jin))) or (yang yi)) shang hai ;".
• Adding a wildcard symbol may retrieve word variants: wan yin yang ((wei chen) or (frei chen)) ((((yang jie) OR (yang jin))) or (yang yi)) shang hai ;*.
