Perhaps you should try some spelling variations:
when adding » why adding, when handling, when adapting
data based » data used
zhang ming » zhang xin
chang hsun » chang ch'un, chung hsuan, chang su
gang data » ring data
di gang » ii gang, d gang, i gang
yang » lang, wang

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