Perhaps you should try some spelling variations:
thanh vai » thanh hai, thanh van, thanh tai
ban thanh » ban hanh, ban hang
ve triet » va trien, su triet
thi hang » thi nang, thi hong, thi thanh
thi hanh » thi thanh
hieu van » hieu va, thien van, lieu va
cua tre » cua te, cuu tre, cua triet
so sach » so sanh, bo sach, co sach
xuc ban » duc ban, cuc ban, quoc ban
van cam » van nam, van lam, van cau

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

• Performing a fuzzy search may retrieve terms with similar spellings: so sach ((thi hang) OR (thi hanh)) xa hoi. hieu van cam xuc ban thanh vai ((cua tre) or (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ((thi hang) OR (thi hanh)) xa hoi. hieu van cam xuc ban thanh vai ((cua tre) OR (ve triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ((thi hang) OR (thi hanh)) xa hoi. hieu van cam xuc ban thanh vai ((cua tre) or (ve triet))".
• Adding a wildcard symbol may retrieve word variants: so sach ((thi hang) OR (thi hanh)) xa hoi. hieu van cam xuc ban thanh vai ((cua tre) or (ve triet))*.
