Perhaps you should try some spelling variations:
yang guang » yang yang, yang liang
wang qian » wang qiao, wang qin, wang liang
shen chan » shen chang, chen chuan
zhong hai » zhong tai, shang hai, zhong zhi
yan guan » gan guan, yan yuan, yihan guan
chan min » chan ming, chang min, chan mun
hong hai » shang hai, zhong tai, dang hai

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 qian ((yan guan) OR (yang guang)) shen chan min ((hong hai) OR (zhong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang qian ((yan guan) OR (yang guang)) shen chan min ((hong hai) or (zhong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang qian ((yan guan) OR (yang guang)) shen chan min ((hong hai) or (zhong hai)) ;*.
