Perhaps you should try some spelling variations:
thanh lai » thanh hai, thanh lap, thanh loi
su triet » su viet, su tien, ve triet
xa thanh » va thanh, ha thanh, ta thanh
cac tuc » cac toc, cac tac, cac nuoc
hieu ve » hieu va, hieu van
su sach » so sach
nang ma » tang ma, sang ma, nang cao
vu sach » vu bach, vu khach
y nang » ky nang, ly nang, v nang
cac tu » cac thu, cach tu, cac du

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (vu sach)) y nang ma hoa. hieu ve ((cac tuc) OR (cac tu)) xa thanh lai su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) y nang ma hoa. hieu ve ((cac tuc) OR (cac tu)) xa thanh lai su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu sach)) y nang ma hoa. hieu ve ((cac tuc) OR (cac tu)) xa thanh lai su triet".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (vu sach)) y nang ma hoa. hieu ve ((cac tuc) OR (cac tu)) xa thanh lai su triet*.
