Perhaps you should try some spelling variations:
hanh trung » thanh trung, hanh trang, manh trung
hoc chiet » hoc thiet, hoc hien, hoc viet
hoc nhiet » hoc thiet, hoc nghien, hoc hien
dung cong » dung trong
trung ap » trung cap, trung lap, trung tam
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan ban, toan tai
toan tap » toan ban
ap dung » xay dung, van dung

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((hoc chiet) OR (hoc nhiet)) tach - hanh trung ap dung cong dan ((toan cau) or (toan tap))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chiet) OR (hoc nhiet)) tach - hanh trung ap dung cong dan ((toan cau) OR (toan tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chiet) OR (hoc nhiet)) tach - hanh trung ap dung cong dan ((toan cau) or (toan tap))*".
