nhung cong » dung cong, thong cong, hang cong
hanh mang » nhanh mang, hanh trang, nhanh lang
cua nhung » va nhung
khoan cam » khoa cam, khoan va, phan cam
mang cua » manh cua, dung cua, ban cua
cong san » cong tac
than cap » khan cap, thanh lap, thanh cac

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 sach) OR (chieu sang)) - hanh mang cua nhung cong san ((than cap) OR (khoan cam))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) OR (chieu sang)) - hanh mang cua nhung cong san ((than cap) or (khoan cam))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) OR (chieu sang)) - hanh mang cua nhung cong san ((than cap) or (khoan cam))*.
