Perhaps you should try some spelling variations:
duong cong » dung cong, luong cong, duong trong
chieu tinh » trieu tinh, lieu tinh, chau tinh
doi chieu » doc hieu, doi chi, ho chieu
tranh van » tran van, trinh van, thanh van
tranh va » trang va, trinh va, thanh va
cong dan » cong san, cong tan, huong dan

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

• Performing a fuzzy search may retrieve terms with similar spellings: doi chieu tinh - canh ((tranh va) OR (tranh van)) duong cong dan ((toan ban) or (van ban))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu tinh - canh ((tranh va) OR (tranh van)) duong cong dan ((toan ban) OR (van ban)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu tinh - canh ((tranh va) OR (tranh van)) duong cong dan ((toan ban) or (van ban))".
• Adding a wildcard symbol may retrieve word variants: doi chieu tinh - canh ((tranh va) OR (tranh van)) duong cong dan ((toan ban) or (van ban))*.
