Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, lieu va
thu sach » tu sach, thuat sach, thuoc sach
nang xa » nang x, lang xa, nang ma
van cam » van nam, van lam, van cau
cam duc » cam xuc, cao duc, pham duc
duc ban » duc tan, duc van, dua ban
benh vi » benh va, benh li, kenh vi
benh ve » benh va, benh vien, benh viem
cua tre » cua te, cuu tre, dua tren
y nang » ky nang, ly nang, v nang

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: thu sach y nang xa hoi. hieu van cam duc ban ((benh vi) OR (benh ve)) ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y nang xa hoi. hieu van cam duc ban ((benh vi) OR (benh ve)) ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y nang xa hoi. hieu van cam duc ban ((benh vi) OR (benh ve)) ((cua tre) or (cua triet))*".
