Perhaps you should try some spelling variations:
thien van » thi van
cua triet » su triet, va triet
hanh dai » hanh tai, hanh dao, vanh dai
cua viet » ca viet, hoa viet, cua vat
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
van dau » van dao, phan dau
y nang » ky nang, ly nang, v nang
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa

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 xa hoi. thien van dau ((xuc va) OR (tuc va)) hanh dai ((cua triet) OR (cua viet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. thien van dau ((xuc va) or (tuc va)) hanh dai ((cua triet) OR (cua viet))~".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. thien van dau ((xuc va) or (tuc va)) hanh dai ((cua triet) OR (cua viet))*.
