Perhaps you should try some spelling variations:
phuong thanh » phong thanh, truong thanh, muong thanh
phuong thao » phuong phap, phuong thuc
hanh mang » nhanh mang, hanh trang, nhanh lang
toan ban » van ban
ha tinh » va tinh, may tinh
mang va » mang vua, hang va, bang va
va dung » van dung, va duong, vat dung

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

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((cuu tinh) or (ha tinh)) - hanh mang va dung ((phuong thanh) OR (phuong thao)) toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((cuu tinh) OR (ha tinh)) - hanh mang va dung ((phuong thanh) OR (phuong thao)) toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((cuu tinh) or (ha tinh)) - hanh mang va dung ((phuong thanh) OR (phuong thao)) toan ban".
• Adding a wildcard symbol may retrieve word variants: ho ((cuu tinh) or (ha tinh)) - hanh mang va dung ((phuong thanh) OR (phuong thao)) toan ban*.
