Perhaps you should try some spelling variations:
truc ban » truc dan, truc van, truoc bang
thuc ban » thuoc ban, thuc dan, thu ban
cuu tre » cau tren, cau treo
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
cua tre » cua te, cua triet, dua tren
hanh de » hanh ve, hanh kem
te lai » te tai, te bai
lai ky » sai ky, dai ky
ve cau » ke cau, va cau, ve 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: te lai ky lang xa hoi. hieu ve cau ((truc ban) OR (thuc ban)) hanh de ((cua tre) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te lai ky lang xa hoi. hieu ve cau ((truc ban) OR (thuc ban)) hanh de ((cua tre) or (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: te lai ky lang xa hoi. hieu ve cau ((truc ban) OR (thuc ban)) hanh de ((cua tre) or (cuu tre))*.
