Perhaps you should try some spelling variations:
ban banh » ban hanh, ban anh, ban danh
hieu van » hieu va, thien van, lieu va
tu sach » thu sach, su sach, te sach
cua tre » cuu tre, cua triet, dua tren
lam xuc » lam duoc
sach ty » sach y, sach tu, sach thu
banh vi » hanh vi, ban vi, benh vi
cua te » cua tu
ty ang » ty xang, ty hang, ty anh
ang xa » lang xa, mang xa, dang xay

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

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