Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu ve » hieu va, hieu van
cam thu » nam thu, cac thu, ca thu
va hanh » van hanh, va thanh, va danh
tu san » thu san, tu ban, tu can
san ky » sang ky, van ky, dan ky
cam tu » nam tu, dam tu, tam tu
vi cua » vai cua, di 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: "tu san ky nang x hoi. hieu ve ((cam tu) OR (cam thu)) va hanh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu san ky nang x hoi. hieu ve ((cam tu) OR (cam thu)) va hanh vi cua triet*.
