Perhaps you should try some spelling variations:
jale chen » jane chen, jie chen
kong land » kong hang, kong lyn
li qiang » li xiang, li keqiang, wei qiang
von jale » von jane, von james, von wales
yang jin » yang jie, yang jun, ying jin
yang yi » yang xi, yang jui
von sam » von sa, von sap, von scham

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

• If you are trying to use Boolean operators, they must be ALL CAPS: li qiang von jale chen ((yang jin) OR (((yang yi) OR (yang di)))) ((von sam) OR (kong land)) ;~.
• Adding a wildcard symbol may retrieve word variants: li qiang von jale chen ((yang jin) or (((yang yi) or (yang di)))) ((von sam) or (kong land)) ;*.
