Perhaps you should try some spelling variations:
luu tuan » huu tuan, luu thanh, luu quang
tu sach » thu sach, su sach, te sach
sach ky » sac ky, sach y, sach ty
cua tre » cua te, cuu tre, cua triet
ve cam » ve cham, va cam, ve cai
ve cac » va cac, vien cac
anh vi » hanh vi, anh va, anh ve
vi cua » vai cua, di cua
x hoi » xa hoi, o hoi, x ho

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 ky nang x hoi. hieu ((ve cam) OR (ve cac)) luu tuan anh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang x hoi. hieu ((ve cam) or (ve cac)) luu tuan anh vi cua tre*.
