Perhaps you should try some spelling variations:
thanh trang » thanh trung, hanh trang, thanh thang
chiet tach » chieu sach
trang va » tran van, hang va
va trong » va truong, va thong, va tuong
cong tac » cong ty
than cau » phan cau, than cap, thanh chau
toan cau » toan cao, toan ban, toan tap

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

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chinh sach) or (chiet tach)) - thanh trang va trong cong tac ((than cau) OR (toan cau))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chinh sach) OR (chiet tach)) - thanh trang va trong cong tac ((than cau) OR (toan cau)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chinh sach) or (chiet tach)) - thanh trang va trong cong tac ((than cau) OR (toan cau))".
• Adding a wildcard symbol may retrieve word variants: ho ((chinh sach) or (chiet tach)) - thanh trang va trong cong tac ((than cau) OR (toan cau))*.
