Perhaps you should try some spelling variations:
qin zheng » qian sheng, bin zhang
shang kai » shang hai
wei chen » frei chen, jui chen, yi chen
wei shen » kwei sheng, enwei shen, wei shang
yang jie » yang jin, yang di, yang yi
yang jui » yang judy, yang di, yang yi
wan qin » wang qin, dan qing, wan ming
yang xi » yang di, yang yi

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan qin zheng ((wei chen) OR (wei shen)) ((((yang jie) or (yang xi))) or (yang jui)) shang kai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan qin zheng ((wei chen) OR (wei shen)) ((((yang jie) OR (yang xi))) OR (yang jui)) shang kai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan qin zheng ((wei chen) OR (wei shen)) ((((yang jie) or (yang xi))) or (yang jui)) shang kai ;*".
