Perhaps you should try some spelling variations:
vien cac » vien bach, vien dai, vien da
cua tre » cua te, cuu tre, cua triet
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
van anh » van thanh, tuan anh, van minh
xuc van » duc van, luc van, xuc ban
vi cua » vai cua, di cua
anh vi » hanh vi, anh va, anh ve
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cai » va cai, ve tai, ve cau
ve cac » va cac

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 sac ky lang xa hoi. hieu ((ve cai) OR (((ve cac) OR (vien cac)))) xuc van anh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang xa hoi. hieu ((ve cai) or (((ve cac) OR (vien cac)))) xuc van anh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky lang xa hoi. hieu ((ve cai) or (((ve cac) OR (vien cac)))) xuc van anh vi cua tre*.
