Perhaps you should try some spelling variations:
thanh tung » thanh cong
hien xanh » hien hanh, hien nhanh, chieu xanh
tung tam » trung tam, vung tam, dung tam
tam hung » tam huong, cam hung, tai hung
cong dan » cong san, cong dong, cong tac
cong tan » cong tac, cong san, cong thanh
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: hoc hien xanh - thanh tung tam hung ((((cong dan) OR (cong tan))) or (huong dan)) toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien xanh - thanh tung tam hung ((((cong dan) OR (cong tan))) OR (huong dan)) toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien xanh - thanh tung tam hung ((((cong dan) OR (cong tan))) or (huong dan)) toan ban*".
