Perhaps you should try some spelling variations:
thu sach » tu sach, thuat sach, thuoc sach
ban banh » ban hanh, ban anh, ban thanh
hieu van » hieu va, thien van, lieu va
ban danh » ban doanh, ban hanh, ban dan
cuu tre » cau tren, cau treo
sach ty » sach y, sach tu, sach thu
cau xuc » cam xuc, cau luc, cau truc
van cau » van dau, van hau, van chat
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang
cua tre » cua te, cua triet, 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: thu sach ty nang xa hoi. hieu van cau xuc ((ban banh) or (ban danh)) vai ((cuu tre) OR (cua tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty nang xa hoi. hieu van cau xuc ((ban banh) OR (ban danh)) vai ((cuu tre) OR (cua tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty nang xa hoi. hieu van cau xuc ((ban banh) or (ban danh)) vai ((cuu tre) OR (cua tre))*".
