Perhaps you should try some spelling variations:
phone adding » phone banking, thing adding, when adding
data based » data used
zhang ping » zhang ming, zhang jing, zhang ting
chang hsun » chang ch'un, chung hsuan, chang su
gang data » ring data
yang yi » yang di, yang xi, yang jui
yi gang » ii gang, i gang, li gang

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: yang yi gang data based ((phone adding) OR (zhang ping)) chang hsun ;~.
• Adding a wildcard symbol may retrieve word variants: yang yi gang data based ((phone adding) or (zhang ping)) chang hsun ;*.
