Perhaps you should try some spelling variations:
cheng zhang » cheng han, zhen zhang, chen zheng
jeong shu » jeong su, cong shu
min jeong » kin keong, min hong, mun leong
chen eng » chan eng, chen zheng, chen rong
gan guan » yan guan, quan guan, fan guon
nan gan » nan yan
chen e » chen _, chen wei

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

• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((nan gan) OR (gan guan)) li ((((chen e) OR (chen eng))) OR (cheng zhang)) min jeong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((nan gan) OR (gan guan)) li ((((chen e) or (chen eng))) or (cheng zhang)) min jeong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((nan gan) OR (gan guan)) li ((((chen e) or (chen eng))) or (cheng zhang)) min jeong shu ;*.
