Perhaps you should try some spelling variations:
va thanh » gia thanh, ban thanh, va tinh
thanh ha » thanh hoa, thanh hai, nhanh ha
sach ky » sac ky, sach y, sach ty
cua tre » cua te, cuu tre, cua triet
va nam » van nam, ha nam
va nay » va ngay, va cay
xuc va » duc va, tuc va, luc va
ha cua » hoa cua, hai cua, nha cua
x hoi » xa hoi, o hoi, x ho

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: su ((sach ky) OR (cac ky)) nang x hoi. lieu ((va nam) OR (va nay)) xuc va thanh ha cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) or (cac ky)) nang x hoi. lieu ((va nam) OR (va nay)) xuc va thanh ha cua tre~".
• Adding a wildcard symbol may retrieve word variants: su ((sach ky) or (cac ky)) nang x hoi. lieu ((va nam) OR (va nay)) xuc va thanh ha cua tre*.
