Perhaps you should try some spelling variations:
hanh trung » thanh trung, hanh trang, manh trung
nhung cong » thong cong, hang cong, nhung don
tieu hanh » tiem hanh, tien hanh, tieu danh
trung cua » truong cua, trung tuan, trung cap
dung cong » dung trong
dan than » dan chan, ban than, van than
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: theo ((tieu hanh) OR (dieu hanh)) - hanh trung cua ((nhung cong) or (dung cong)) dan than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((tieu hanh) OR (dieu hanh)) - hanh trung cua ((nhung cong) OR (dung cong)) dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu hanh) OR (dieu hanh)) - hanh trung cua ((nhung cong) or (dung cong)) dan than cau".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu hanh) OR (dieu hanh)) - hanh trung cua ((nhung cong) or (dung cong)) dan than cau*.
