Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu ve » hieu va, hieu van
cham tu » pham tu, cam tu, chai tu
va hanh » van hanh, va thanh, va danh
tu can » tu ban, tu cac, thu canh
can ky » van ky, dan ky, ban ky
dam tu » nam tu, cam 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.

• If you are trying to use Boolean operators, they must be ALL CAPS: tu can ky nang x hoi. hieu ve ((cham tu) OR (dam tu)) va hanh vi cua triet~.
• Adding a wildcard symbol may retrieve word variants: tu can ky nang x hoi. hieu ve ((cham tu) or (dam tu)) va hanh vi cua triet*.
