Perhaps you should try some spelling variations:
yuan cheng » yuan chang, huang cheng, yu cheng
yang yuan » fang yuan, yan yuan, yang yun
shang hai » shang kai, dang hai, chang ha
ran ying » fan ying, tan ying, gao ying
jin ying » li ying
yang jui » yang judy, yang xi
yang yi » 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) OR (jin ying)) yang yuan cheng ((((yang jui) or (yang di))) or (yang yi)) shang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ran ying) OR (jin ying)) yang yuan cheng ((((yang jui) OR (yang di))) OR (yang yi)) shang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ran ying) OR (jin ying)) yang yuan cheng ((((yang jui) or (yang di))) or (yang yi)) shang hai ;*".
