Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
cac tuc » cac toc, cac tac, cac nuoc
nang ji » nang si, nang noi, nang tai
va nang » van nang, da nang, cam nang
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
ji cua » di cua
cac tu » cac thu, cach tu, cac du
tu sac » tu sach, tu cac, tu bac
tu san » thu san, tu ban, tu can

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