Perhaps you should try some spelling variations:
dung thuong » dung trong, hang thuong, cong thuong
hien nhanh » hien hanh, thien thanh, tien thanh
hanh trung » thanh trung, hanh trang, manh trung
hien xanh » hien hanh, chieu xanh, hien khanh
trung ap » trung cap, trung lap, trung tam
dan than » dan chan, ban than, dan toan
van than » van thanh, van thang, van tuan
ap dung » xay dung, van dung

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 xanh) or (hien nhanh)) - hanh trung ap dung thuong ((dan than) OR (van than)) man~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien xanh) OR (hien nhanh)) - hanh trung ap dung thuong ((dan than) OR (van than)) man.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) or (hien nhanh)) - hanh trung ap dung thuong ((dan than) OR (van than)) man".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (hien nhanh)) - hanh trung ap dung thuong ((dan than) OR (van than)) man*.
