Perhaps you should try some spelling variations:
zhang ming » zhang xin
chang min » chang mae, chan ming, chang ann
jeong shu » jeong su, cong shu
wang dan » wang yan, wang ban, wang yidan
dan yan » dan yang, nan yan, wang yan
zi chen » zhi chen, yi chen, li chen
yan zi » yan zhi, yuan zi, ban zi

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 dan yan zi chen ((chang min) OR (zhang ming)) jeong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang dan yan zi chen ((chang min) OR (zhang ming)) jeong shu ;*.
