Perhaps you should try some spelling variations:
basic postal » basic cost, basic costs
sharing data » sharing a
lang tan » liang tan, lang lang, tang tang
tan ying » fan ying, ran ying, tan yang
can lost » can cost, can lose, can post
can cash » a cash
tax she » tax side

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: lang tan ying ((((can lost) OR (basic postal))) OR (can cash)) sharing data tax she ;~.
• Adding a wildcard symbol may retrieve word variants: lang tan ying ((((can lost) or (basic postal))) or (can cash)) sharing data tax she ;*.
