Perhaps you should try some spelling variations:
nhung cong » thong cong, hang cong, nhung don
tieu hanh » dieu hanh, tiem hanh, tieu danh
tien hanh » tien thanh, hien hanh, tien anh
manh hung » anh huong
dung cong » dung trong
hung cua » huong cua, chung cua, khung cua
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((tieu hanh) OR (tien hanh)) - manh hung cua ((nhung cong) OR (dung cong)) dan than cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((tieu hanh) or (tien hanh)) - manh hung cua ((nhung cong) or (dung cong)) dan than cau*.
