Perhaps you should try some spelling variations:
thanh sinh » thanh binh, thanh tinh, thanh vinh
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
va thanh » gia thanh, ban thanh, va tinh
hieu van » thien van, lieu va, hieu ve
tu sach » thu sach, su sach, te sach
hieu va » lieu va, hieu qua
lam tuc » lam thuoc, lam truoc, luat tuc
tuc va » thuc va, truc va, tuc xa
y nang » ky nang, ly nang, v nang
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: tu sach y nang x hoi. ((hieu van) OR (hieu va)) lam tuc va thanh sinh ((cua triet) OR (su triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang x hoi. ((hieu van) OR (hieu va)) lam tuc va thanh sinh ((cua triet) or (su triet))~".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang x hoi. ((hieu van) OR (hieu va)) lam tuc va thanh sinh ((cua triet) or (su triet))*.
