Perhaps you should try some spelling variations:
thanh lai » thanh hai, thanh lap, thanh loi
sach ky » sac ky, sach y, sach ty
lai cuu » lai cua, lai chau, lai cuoc
tu sach » thu sach, su sach, te sach
ve cham » va cham, ve chat, vu cham
hieu ve » hieu va, hieu van
cuu tre » cua tre, cau tren, cau treo
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa
x hoi » o hoi, x ho, 5 hoi

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) OR (xa hoi)). hieu ve cham ((xuc va) OR (tuc va)) thanh lai cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang ((x hoi) OR (xa hoi)). hieu ve cham ((xuc va) or (tuc va)) thanh lai cuu tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang ((x hoi) OR (xa hoi)). hieu ve cham ((xuc va) or (tuc va)) thanh lai cuu tre*.
