Perhaps you should try some spelling variations:
ve triet » va trien, su triet
va triet » va thiet, va trien, cua triet
pham tu » phan tu, pham thi, pham tai
nang mo » nang meo, nang ma, nang co
hieu ve » hieu va, hieu van
cham tu » cam tu, chai tu, chay tu
va hanh » van hanh, va thanh, va danh
tu san » thu san, tu ban, tu can
san ky » sang ky, van ky, dan ky
mo hoi » mo phoi, mo hoc, co hoi

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 san ky nang mo hoi. hieu ve ((cham tu) OR (pham tu)) va hanh vi ((va triet) OR (ve triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky nang mo hoi. hieu ve ((cham tu) or (pham tu)) va hanh vi ((va triet) OR (ve triet))~".
• Adding a wildcard symbol may retrieve word variants: tu san ky nang mo hoi. hieu ve ((cham tu) or (pham tu)) va hanh vi ((va triet) OR (ve triet))*.
