Perhaps you should try some spelling variations:
chen zheng » chen aizheng, cheng zhang, chen zhe
yan liang » yang liang, wang liang, you liang
chen zhen » chen zhe
rong kong » hong kong, king kong, sing kong
wang nan » wang yan, wang ban, wang dan
kong shu » cong shu, kong siu, tong shui
nan yan » nan ya, wang yan, qian yan

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 nan yan liang ((chen zheng) OR (chen zhen)) rong kong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang nan yan liang ((chen zheng) OR (chen zhen)) rong kong shu ;*.
