shang kai » shang hai
ran ying » fan ying, tan ying, jin ying
yu cheng » yu chen, _ cheng
yang jui » yang judy, yang di, yang xi

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 yang ((yuan cheng) OR (yu cheng)) ((((yang jui) or (yang jie))) or (yang yi)) shang kai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ran ying yang ((yuan cheng) OR (yu cheng)) ((((yang jui) OR (yang jie))) OR (yang yi)) shang kai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ran ying yang ((yuan cheng) OR (yu cheng)) ((((yang jui) or (yang jie))) or (yang yi)) shang kai ;*".
