Perhaps you should try some spelling variations:
zhang yan » zhang jian, wang yan
kong john » king john, wong john, longo john
wong sam » wong sau, wong lai, kong sar
yang li » yang lin, yang di, yang xi
li kong » li cong, li rong, li song
li li » li lin, li l, li lu
shin » skin, sein, thin

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: ((zhang yan) OR (zhang fan)) yang li li kong john ((wong sam) OR (song shin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((zhang yan) OR (zhang fan)) yang li li kong john ((wong sam) or (song shin)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((zhang yan) OR (zhang fan)) yang li li kong john ((wong sam) or (song shin)) ;*.
