Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
van thanh » ban thanh, van tuan
thanh di » thanh doi, thanh de, thanh do
su triet » su viet, su tien, ve triet
te sach » toc sach
xang xa » lang xa, mang xa, ang xa
cam tuc » cam tu, nam thuc, dam thuc
y xang » ty xang

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: te sach y xang xa hoi. hieu qua ((cam tuc) OR (cam xuc)) van thanh di ((cua triet) OR (su triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y xang xa hoi. hieu qua ((cam tuc) or (cam xuc)) van thanh di ((cua triet) OR (su triet))~".
• Adding a wildcard symbol may retrieve word variants: te sach y xang xa hoi. hieu qua ((cam tuc) or (cam xuc)) van thanh di ((cua triet) OR (su triet))*.
