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
hieu van » hieu va, thien van, lieu va
tuc gia » tac gia, duc gia, toc gia
tu sach » thu sach, su sach, te sach
lam tuc » lam thuoc, lam truoc, luat tuc
ly nang » ky nang, ly hang, ly vang
van lam » van nam
y nang » ky nang, v nang, may 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) OR (ly nang)) x hoi. hieu van lam tuc gia thanh sinh ((cua triet) OR (su triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y nang) OR (ly nang)) x hoi. hieu van lam tuc gia thanh sinh ((cua triet) or (su triet))~".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y nang) OR (ly nang)) x hoi. hieu van lam tuc gia thanh sinh ((cua triet) or (su triet))*.
