Perhaps you should try some spelling variations:
cua triet » su triet, va triet
cua viet » ca viet, hoa viet, cua vat
hieu ve » hieu va, hieu van
ve pham » vi pham, v pham, ve phan
pham tu » phan tu, pham thi, pham tai
va hanh » van hanh, va thanh, va danh
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: "tu van ky nang x hoi. hieu ve pham tu va hanh vi ((cua triet) OR (cua viet))~".
• Adding a wildcard symbol may retrieve word variants: tu van ky nang x hoi. hieu ve pham tu va hanh vi ((cua triet) OR (cua viet))*.
