Perhaps you should try some spelling variations:
thanh tung » thanh cong
hoc chieu » hoc thieu, hoc hien, hoc dieu
ho chieu » theo chieu, hoc thieu, doi chieu
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan ban » van ban
tung ap » tang ap, tung dan, tung bay
ap dung » xay dung, van dung

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (ho chieu)) tinh - thanh tung ap dung ((cong dan) OR (cong tan)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) OR (ho chieu)) tinh - thanh tung ap dung ((cong dan) or (cong tan)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) OR (ho chieu)) tinh - thanh tung ap dung ((cong dan) or (cong tan)) toan ban*.
