Perhaps you should try some spelling variations:
china's real » china's rural, china's great, china's coal
china's road » china's role, china's rural, china's rise
long sin » dong sin, long span, long run
sin dann » sein dann, bin dann, ein dank
yang jie » yang jin, yang di, yang jui
wang hui » wang hua, wang zhi, wang wei

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: long sin dann ((china's real) OR (china's road)) yang jie ((tong hui) OR (wang hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "long sin dann ((china's real) OR (china's road)) yang jie ((tong hui) or (wang hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: long sin dann ((china's real) OR (china's road)) yang jie ((tong hui) or (wang hui)) ;*.
