Perhaps you should try some spelling variations:
cua triet » su triet, va triet
cua viet » ca viet, hoa viet, cua vat
te sach » toc sach
hieu ve » hieu va, hieu van
cam tuc » cam xuc, cam tu, nam thuc
anh tai » hanh tai, anh thai, vanh tai
y nang » ky nang, ly nang, v nang
ve cam » ve cham, ve cac, va cam
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 ve cam tuc va ((anh tai) or (doanh tai)) ((cua triet) OR (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang x hoi. hieu ve cam tuc va ((anh tai) OR (doanh tai)) ((cua triet) OR (cua viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang x hoi. hieu ve cam tuc va ((anh tai) or (doanh tai)) ((cua triet) OR (cua viet))*".
