Perhaps you should try some spelling variations:
xang tao » sang tao, nang tao, vang tao
chua tre » chua tri, chua trieu, cho tre
tu sach » thu sach, su sach, te sach
hanh va » hang va, hanh vi
cua tre » cua te, cuu tre, cua triet
sach ty » sach y, sach tu, sach thu
hieu ve » hieu va, hieu van
tao hoi » tao khoi, tao boi, tay hoi
tuc va » thuc va, truc va, tuc xa
xuc va » duc va, luc va, xac va
ve cam » ve cham, ve cac, va cam

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 xang tao hoi. hieu ve cam ((xuc va) OR (tuc va)) hanh va ((chua tre) OR (cua tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty xang tao hoi. hieu ve cam ((xuc va) OR (tuc va)) hanh va ((chua tre) or (cua tre))~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty xang tao hoi. hieu ve cam ((xuc va) OR (tuc va)) hanh va ((chua tre) or (cua tre))*.
