Perhaps you should try some spelling variations:
hanh tai » thanh tai, hang tai, han tai
tu sach » thu sach, su sach, te sach
xuc van » duc van, xuc ban, thuc van
tai cua » thai cua, tai cuc, tri cua
luc van » luoc van, luu van, duc van
cua tre » cua te, cuu tre, cua triet
hieu ve » hieu va, hieu van
y nang » ky nang, ly nang, v nang
c_ hai » co hai
ve cac » va cac, vien 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 sach y nang ((_ hai) OR (c_ hai)). hieu ve cac ((xuc van) OR (luc van)) hanh tai cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu sach y nang ((_ hai) or (c_ hai)). hieu ve cac ((xuc van) or (luc van)) hanh tai cua tre*.
