Perhaps you should try some spelling variations:
hanh trang » thanh trung, canh tranh, hanh trinh
hoc thieu » toc thieu, hoc hien
trang vat » trang va, trang vai, tang vat
doc hieu » toc thieu, hoc hien
vat dung » van dung, va dung, viet dung
cong dan » cong san, cong tan, cong dong
toan ban » van ban

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((doc hieu) or (hoc thieu)) xanh - hanh trang vat dung ((cong dan) OR (huong dan)) toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((doc hieu) OR (hoc thieu)) xanh - hanh trang vat dung ((cong dan) OR (huong dan)) toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc hieu) or (hoc thieu)) xanh - hanh trang vat dung ((cong dan) OR (huong dan)) toan ban".
• Adding a wildcard symbol may retrieve word variants: ((doc hieu) or (hoc thieu)) xanh - hanh trang vat dung ((cong dan) OR (huong dan)) toan ban*.
