Perhaps you should try some spelling variations:
khong cong » thong cong, khong cang, chong cong
chieu xanh » chieu sach, chieu sang, chieu tinh
tieu xanh » tieu danh, dieu hanh, tien anh
huong cua » dung cua
mang cua » manh cua, dung cua, ban cua
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan tap » toan ban

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: theo ((tieu xanh) OR (chieu xanh)) - hanh ((mang cua) OR (huong cua)) khong cong tan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu xanh) OR (chieu xanh)) - hanh ((mang cua) or (huong cua)) khong cong tan toan tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu xanh) OR (chieu xanh)) - hanh ((mang cua) or (huong cua)) khong cong tan toan tap*.
