Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
sach ty » sach y, sach tu, sach thu
ty hang » ly hang, ty xang, thi hang
hang xa » hoang xa, hang va, hang ca
hieu va » lieu va, hieu qua
va cham » va chat, va tham
tuc va » thuc va, truc va, duc va
vi cua » vai cua, di cua
cua tu » cua tuc, cua su, cua cu

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