Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hoc sach » hoc sinh, hoc cac, hoc anh
cham duc » pham duc, pham duy, phan duc
ban hanh » ban hang
sach ky » sac ky, sach y, sach ty
hanh di » hanh vi, hanh de, hang di
di cua » dai cua, doi cua, de cua
x hoi » xa hoi, o hoi, x ho

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sach ky nang x hoi. lieu va ((cham duc) OR (cham soc)) ban hanh di cua triet~".
• Adding a wildcard symbol may retrieve word variants: hoc sach ky nang x hoi. lieu va ((cham duc) OR (cham soc)) ban hanh di cua triet*.
