Perhaps you should try some spelling variations:
things zeng » things zhang, things end, things using
time past » time part, time pad
some past » some case
tan kong » tan hong
kong wah » yong wah, kong nach, kong weak
doug bin » dong bin, dort bin
org bin » dong bin, dort bin

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

• Performing a fuzzy search may retrieve terms with similar spellings: tan kong wah ((time past) OR (some past)) things zeng ((doug bin) or (org bin)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tan kong wah ((time past) OR (some past)) things zeng ((doug bin) OR (org bin)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tan kong wah ((time past) OR (some past)) things zeng ((doug bin) or (org bin)) ;*".
