Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
hieu xanh » chieu xanh, hieu nganh, dieu hanh
hieu manh » chieu xanh, hieu nganh, dieu hanh
trinh cua » tinh cua, trinh luat, trinh quan
cong tanh » cong thanh, cong tinh, cong danh
cua bang » chua bang, cua ban, cua dang
cong tan » cong tac, cong san, cong thanh
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: doc ((hieu xanh) OR (hieu manh)) - hanh trinh cua bang ((cong tanh) OR (cong tan)) toan cao~.
• Adding a wildcard symbol may retrieve word variants: doc ((hieu xanh) or (hieu manh)) - hanh trinh cua bang ((cong tanh) or (cong tan)) toan cao*.
