Perhaps you should try some spelling variations:
hieu nganh » vien nganh, hiem ngan, nghiep nganh
hanh trang » thanh trung, canh tranh, hanh trinh
thuat hung » thuat dung, thuat xung, thuat chuong
hieu manh » chieu xanh, dieu hanh, hien hanh
thuat ung » thuat dung, thuat xung, thuat song
duong ban » duong van, dong ban, duong san
ban than » ban thanh, van thanh, ban hang
than cau » toan cau, phan cau, than cap

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((hieu manh) or (hieu nganh)) - hanh trang ((thuat hung) OR (thuat ung)) duong ban than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hieu manh) OR (hieu nganh)) - hanh trang ((thuat hung) OR (thuat ung)) duong ban than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hieu manh) or (hieu nganh)) - hanh trang ((thuat hung) OR (thuat ung)) duong ban than cau*".
