Perhaps you should try some spelling variations:
nhung chong » nhung cong, nhung phong, nhung phuong
khung cong » nhung cong, khung long, phung cong
hien manh » tien manh, hieu manh, hien nhanh
hien hanh » dieu hanh
huong dai » huong dan, huong doi, duong dai
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((hien manh) OR (hien hanh)) - anh huong dai ((khung cong) or (nhung chong)) dan than cap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien manh) OR (hien hanh)) - anh huong dai ((khung cong) OR (nhung chong)) dan than cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien manh) OR (hien hanh)) - anh huong dai ((khung cong) or (nhung chong)) dan than cap".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien manh) OR (hien hanh)) - anh huong dai ((khung cong) or (nhung chong)) dan than cap*.
