Perhaps you should try some spelling variations:
xa thanh » va thanh, ha thanh, ta thanh
thanh vi » hanh vi, thanh va, thanh ve
su sach » so sach, vu sach
sach ty » sach y, sach tu, sach thu
ty nang » ky nang, ty xang, ty hang
nang xa » nang x, lang xa, nang ma
van cac » van hac, van bac, dan cac
van cau » van dau, van hau, van chat
cua tre » cua te, cuu tre, cua triet
vi cua » vai cua, di cua

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: su sach ty nang xa hoi. hieu ((van cac) OR (van cau)) tuc xa thanh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: su sach ty nang xa hoi. hieu ((van cac) or (van cau)) tuc xa thanh vi cua tre*.
