Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
thanh vai » thanh hai, thanh van, thanh tai
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, lieu va
sach ty » sach tu, sach thu, xach tay
hang xa » hoang xa, hang va, hang ca
van cam » van nam, van lam, van cau
xuc ban » duc ban, cuc ban, quoc ban
cua tre » cua te, cuu tre, dua tren

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