Perhaps you should try some spelling variations:
hieu ve » hieu va, hieu van
cham tu » pham tu, chai tu, chay tu
va hanh » van hanh, va thanh, va danh
vai cua » dai cua, hai cua, lai cua
tu can » tu ban, tu cac, thu canh
can ky » van ky, dan ky, ban ky
cam tu » cam thu, nam tu, dam tu
vi 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 (cam tu)) va hanh ((vi cua) OR (vai cua)) triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu can ky nang x hoi. hieu ve ((cham tu) or (cam tu)) va hanh ((vi cua) OR (vai cua)) triet~".
• Adding a wildcard symbol may retrieve word variants: tu can ky nang x hoi. hieu ve ((cham tu) or (cam tu)) va hanh ((vi cua) OR (vai cua)) triet*.
