Perhaps you should try some spelling variations:
gao shang » gao zhong, hao zhang
shang hai » shang kai, dang hai, chang ha
yang yue » wang yue, yang yun, yang jui
tan yang » dan yang, tan ying, tan yong
yang gao » yang yao, yang fan, xing gao
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 hyoung ((yan kun) OR (yang yue)) tan yang gao shang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang hyoung ((yan kun) or (yang yue)) tan yang gao shang hai ;*.
