Perhaps you should try some spelling variations:
sang tao » hang tai
chua tre » chua tri, cua tre, chua trieu
sach tu » sach thu, cach tu, sach uu
hanh va » hang va
cam tuc » cam xuc, cam tu, nam thuc
hieu ve » hieu va, hieu van
sach ty » sach y, sach thu, xach tay
tuc va » thuc va, truc va, tuc xa
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: te ((sach tu) OR (sach ty)) sang tao boi. hieu ve cam tuc va ((hanh va) OR (hanh vi)) chua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach tu) OR (sach ty)) sang tao boi. hieu ve cam tuc va ((hanh va) or (hanh vi)) chua tre~".
• Adding a wildcard symbol may retrieve word variants: te ((sach tu) OR (sach ty)) sang tao boi. hieu ve cam tuc va ((hanh va) or (hanh vi)) chua tre*.
