Perhaps you should try some spelling variations:
young john » wong john, young jean
ping wang » ping pong, hong wang
kong john » king john, wong john, longo john
wong sau » wong siu, wong shiu, wong lai
wong sam » wong lai, kong sar, von sam
li lu » li ju, li li, li wu
li l » li li, li _, i l

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: ping wang yanling ((li l) OR (li lu)) ((young john) OR (kong john)) ((wong sau) OR (wong sam)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ping wang yanling ((li l) OR (li lu)) ((young john) or (kong john)) ((wong sau) or (wong sam)) ;~".
• Adding a wildcard symbol may retrieve word variants: ping wang yanling ((li l) OR (li lu)) ((young john) or (kong john)) ((wong sau) or (wong sam)) ;*.
