shang kai » shang hai
yin hang » yin fang, yin yang, ying chang
yun chen » yu chen, yuan cheng, yulu chen
yang jie » yang jin, yang di, yang jui
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 hang ((yung chen) OR (yun chen)) ((((yang judy) or (yang jie))) or (yang yi)) shang kai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan yin hang ((yung chen) OR (yun chen)) ((((yang judy) OR (yang jie))) OR (yang yi)) shang kai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yin hang ((yung chen) OR (yun chen)) ((((yang judy) or (yang jie))) or (yang yi)) shang kai ;*".
