Perhaps you should try some spelling variations:
nhanh chong » thanh cong, khanh phong
nganh cong » thanh cong
hanh tang » hanh trang, anh tang, hanh mang
tang chuc » cong chuc, tang cua, tang khu
theo yeu » theo tieu, thiet yeu, theo chu
dan toan » van toan, dan than, manh toan
toan ban » van ban
theo te » theo tu, theo tieu

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((theo te) OR (theo yeu)) sach - hanh tang chuc ((nganh cong) or (nhanh chong)) dan toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo te) OR (theo yeu)) sach - hanh tang chuc ((nganh cong) OR (nhanh chong)) dan toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo te) OR (theo yeu)) sach - hanh tang chuc ((nganh cong) or (nhanh chong)) dan toan ban*".
