Perhaps you should try some spelling variations:
liang chen » liang choon, chang chen, kang chen
yan liang » yang liang, wang liang, you liang
chen zhen » chen zhe
zhen rong » zheng rong, chen rong, zhen yong
wang nan » wang yan, wang ban, wang dan
kong shu » kong siu, tong shui, kong sar
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 zhen rong ((kong shu) OR (cong shu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang nan yan liang chen zhen rong ((kong shu) OR (cong shu)) ;*.
