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