Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
qua cham » qua hai, qua cac, va cham
cham tuc » nham thuc, pham thuc, tham thuc
su triet » su viet, su tien, ve triet
so sach » so sanh, bo sach, co sach
ky dang » ky nang
ky danh » ky anh
va hanh » van hanh, va thanh, va danh
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: so sach ((ky dang) OR (ky danh)) xa hoi. hieu qua cham tuc va hanh vi ((cua triet) OR (su triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ((ky dang) or (ky danh)) xa hoi. hieu qua cham tuc va hanh vi ((cua triet) OR (su triet))~".
• Adding a wildcard symbol may retrieve word variants: so sach ((ky dang) or (ky danh)) xa hoi. hieu qua cham tuc va hanh vi ((cua triet) OR (su triet))*.
