Perhaps you should try some spelling variations:
taking business » making business, taxing business, banking business
wang shiyong » wang hyoung
doing und » ding und, doing un, ring und
dong bin » dong sin, dong di, dann bin
hong ea » hong ma, hong seo, hong tan
hong a » hong ma, hong w, kong a

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: wang shiyong ((hong ea) OR (hong a)) data taking business ((doing und) OR (dong bin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang shiyong ((hong ea) OR (hong a)) data taking business ((doing und) or (dong bin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang shiyong ((hong ea) OR (hong a)) data taking business ((doing und) or (dong bin)) ;*.
