Perhaps you should try some spelling variations:
thanh lai » thanh hai, thanh lap, thanh loi
ban thanh » ban hanh, ban hang
cua triet » cua viet, su triet, va triet
thu sach » tu sach, thuat sach, thuoc sach
hieu van » hieu va, thien van, lieu va
cuu thuc » cuu tac
thuc ban » thuoc ban, thuc dan, thu ban
sach ty » sach y, sach tu, sach thu
ty nang » ky nang, ty xang, ty hang
nang xa » nang x, lang xa, nang ma
van cuu » van cau, van chu, van cu
cua tre » cua te, cuu tre, dua tren

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: thu sach ty nang xa hoi. hieu van cuu thuc ban thanh lai ((cua tre) OR (cua triet))~.
• Adding a wildcard symbol may retrieve word variants: thu sach ty nang xa hoi. hieu van cuu thuc ban thanh lai ((cua tre) or (cua triet))*.
