Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
thi chieu » thi chien, thi hieu, theo chieu
tranh cua » doanh cua
ho chieu » theo chieu, hoc thieu, doi chieu
manh cua » doanh cua, ban cua
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan cau » toan cao, toan ban, toan tap

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: ((ho chieu) OR (thi chieu)) sach - canh ((tranh cua) OR (manh cua)) nhung cong tan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (thi chieu)) sach - canh ((tranh cua) OR (manh cua)) nhung cong tan toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (thi chieu)) sach - canh ((tranh cua) OR (manh cua)) nhung cong tan toan cau*.
