Perhaps you should try some spelling variations:
thien van » thi van
cua triet » cua viet, su triet, va triet
sach van » sach han, sach va, bach van
van nang » van quang, van ban, van dong
van hanh » van thanh, ban hanh, van anh
su sach » so sach, vu sach
hanh di » hanh vi, hanh de, hang di
su tien » su kien, su hien, tu tieng
cau xuc » cau luc, cau truc, chat xuc
nang xa » nang x, lang xa, nang ma

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: su sach van nang xa hoi. thien van ((cau xuc) OR (cam xuc)) van hanh di ((cua triet) or (su tien))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach van nang xa hoi. thien van ((cau xuc) OR (cam xuc)) van hanh di ((cua triet) OR (su tien))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach van nang xa hoi. thien van ((cau xuc) OR (cam xuc)) van hanh di ((cua triet) or (su tien))*".
