Perhaps you should try some spelling variations:
phone adding » phone banking, thing adding, when adding
chung hsuan » chung chuan, chang hsun, hung hsun
data based » data used
zhang ming » zhang xin
di gang » ii gang, i gang, li gang
d gang » 2 gang, _ gang, b gang
yang » lang, wang

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

• Performing a fuzzy search may retrieve terms with similar spellings: yang ((di gang) OR (d gang)) data based ((phone adding) or (zhang ming)) chung hsuan ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: yang ((di gang) OR (d gang)) data based ((phone adding) OR (zhang ming)) chung hsuan ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang ((di gang) OR (d gang)) data based ((phone adding) or (zhang ming)) chung hsuan ;*".
