Perhaps you should try some spelling variations:
hieu nganh » vien nganh, hiem ngan, hieu manh
hieu lang » chieu sang, hieu quang, nhieu tang
hanh mang » nhanh mang, hanh trang, nhanh lang
cua nhung » va nhung
cua hang » cua dang, cua cong, cua ban
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: theo ((hieu nganh) OR (hieu lang)) - hanh mang ((cua hang) OR (cua nhung)) cong tan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((hieu nganh) or (hieu lang)) - hanh mang ((cua hang) OR (cua nhung)) cong tan toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((hieu nganh) or (hieu lang)) - hanh mang ((cua hang) OR (cua nhung)) cong tan toan cau*.
