Perhaps you should try some spelling variations:
sach ty » sach y, sach tu, sach thu
sach uu » sach luu, sach tu, sach xu
hang xa » hoang xa, hang va, hang ca
hieu ve » hieu va, hieu van
cam tuc » cam xuc, cam tu, nam thuc
xa hanh » xa thanh, xa khanh, va hanh
ve cam » ve cham, ve cac, va cam
cua te » cua tu
cua su » qua su

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) OR (sach uu)) hang xa hoi. hieu ve cam tuc xa hanh vi ((cua te) OR (cua su))~.
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) or (sach uu)) hang xa hoi. hieu ve cam tuc xa hanh vi ((cua te) or (cua su))*.
