Perhaps you should try some spelling variations:
thinking john » thinking can, thinking form, thinking four
data thinking » data linking, data taking, a thinking
did chinas » did chinese, ii chinas
john gong » john song, john wong, john ogony
gong meng » gong gang, gong min
dong bin » dong di, dann bin

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: ((dong sin) OR (dong bin)) ((did chinas) OR (did china's)) data thinking john gong meng ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong sin) or (dong bin)) ((did chinas) OR (did china's)) data thinking john gong meng ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong sin) or (dong bin)) ((did chinas) OR (did china's)) data thinking john gong meng ;*.
