Perhaps you should try some spelling variations:
thin zeng » thin end, thin lens
last thin » last thing, last things
soon ang » hoong ang, soon beng, soon heng
iii last » iii list, iii liste, iii waste
doug bin » dort bin, org bin
dong bin » dong di, dann bin
sun ang » sun qiang
sin » sign, sind, skin

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: nina ((sun ang) OR (soon ang)) iii last thin zeng ((((doug bin) OR (dong bin))) OR (dong sin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nina ((sun ang) OR (soon ang)) iii last thin zeng ((((doug bin) or (dong bin))) or (dong sin)) ;~".
• Adding a wildcard symbol may retrieve word variants: nina ((sun ang) OR (soon ang)) iii last thin zeng ((((doug bin) or (dong bin))) or (dong sin)) ;*.
