Perhaps you should try some spelling variations:
cheng zhang » cheng han, zhen zhang, chen zheng
zhang xin » zhang jian, zhang ming, zhang fan
yan yuan » yan guan, fang yuan, yan clan
li cheng » li chen, xi cheng, lei sheng
tong shu » tong shui, cong shu, wong shiu
nan yan » nan ya, wang yan, qian yan
wang » wing, wan, lang

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 ((yan yuan) OR (nan yan)) li cheng zhang xin tong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yuan) OR (nan yan)) li cheng zhang xin tong shu ;*.
