Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
gain yang » dan yang, daun yang, yin yang
yang yun » yang jun, tang yun, yang yue
tan yang » dan yang, tan ying, tan yong
gang hai » dang hai, eang hay, gang hu
yan kun » yan guan, yan yuan
wang » wing, wan, lang

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 yan ((yan kun) OR (yang yun)) ((gain yang) OR (tan yang)) gai ((gang hai) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((yan kun) or (yang yun)) ((gain yang) or (tan yang)) gai ((gang hai) OR (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((yan kun) or (yang yun)) ((gain yang) or (tan yang)) gai ((gang hai) OR (shang hai)) ;*.
