Perhaps you should try some spelling variations:
chen chung » chen chuling, chen shuang, chen chuan
kong zhong » kong hong, hong hong, kong hang
wang qian » wang qiao, wang qin, wang liang
qian wang » yiqian wang, qian rong, qian yan
chen chan » chen chuan, cheung chan, shen chang
zhong zhi » zhang zhi, hong ghi, zhong tai

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang qian wang yan ((chen chan) OR (chen chung)) kong zhong zhi ;~".
• Adding a wildcard symbol may retrieve word variants: wang qian wang yan ((chen chan) OR (chen chung)) kong zhong zhi ;*.
