Perhaps you should try some spelling variations:
cua tre » cua te, cuu tre, cua triet
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
luc van » luoc van, luu van, duc van
xuc van » duc van, xuc ban, thuc van
vi cua » vai cua, di cua
tu sac » tu sach, tu cac, tu san
ve cac » va cac, vien cac
sac ky » cac ky, sai ky
ve cai » va cai, ve tai, ve cau

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)) ((xuc van) OR (luc van)) hanh 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)) ((xuc van) OR (luc van)) hanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky lang xa hoi. hieu ((ve cai) or (ve cac)) ((xuc van) OR (luc van)) hanh vi cua tre*.
