Perhaps you should try some spelling variations:
costs missing » costs timing, costs using
costs arising » costs driving, losses arising, costs timing
test housing » cost housing, test using, era housing
wang liang » wang yang
bang dai » zhang dai
wang li » wang lei, wang lin, tang li

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 liang ((bang dai) OR (wang li)) test housing ((costs missing) OR (costs arising)) un ;~.
• Adding a wildcard symbol may retrieve word variants: wang liang ((bang dai) or (wang li)) test housing ((costs missing) or (costs arising)) un ;*.
