Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
tang ky » dang ky, trong ky, tang khu
sang ky » sang kyo, dang ky, bang ky
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
va hanh » van hanh, va thanh, va danh
san ky » van ky, dan ky, ban ky
ve nam » he nam, va nam, le nam
nam tu » nam thu, nam thuc
vi cua » vai cua, di cua

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