Perhaps you should try some spelling variations:
yiqian wang » yijiang wang, liqin wang
qian wang » qian rong, qian yan, yan wang
shang kai » shang hai
tan yang » tan ying, tan yong, tao yang
dan yang » daun yang, wang yang, yang yang
gang hai » dang hai, shang hai, eang hay
jing ji » ying jin

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: ((qian wang) OR (yiqian wang)) jing ji ((tan yang) OR (dan yang)) li ((gang hai) OR (shang kai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((qian wang) OR (yiqian wang)) jing ji ((tan yang) or (dan yang)) li ((gang hai) or (shang kai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((qian wang) OR (yiqian wang)) jing ji ((tan yang) or (dan yang)) li ((gang hai) or (shang kai)) ;*.
