Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
va thanh » gia thanh, ban thanh, va tinh
thanh de » hanh de, thanh ve, thanh do
te sach » toc sach
van cam » van nam, van cau, van dam
van lam » van nam
cua tre » cua te, cuu tre, dua tren
y nang » ky nang, ly nang, v nang
tuc va » thuc va, truc va, tuc xa
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang x hoi. hieu ((van cam) or (van lam)) tuc va thanh de ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang x hoi. hieu ((van cam) OR (van lam)) tuc va thanh de ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang x hoi. hieu ((van cam) or (van lam)) tuc va thanh de ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: te sach y nang x hoi. hieu ((van cam) or (van lam)) tuc va thanh de ((cua tre) OR (cua triet))*.
