Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
va thanh » gia thanh, ban thanh, va tinh
su triet » su viet, su tien, ve triet
va chai » va cai, va chat, va cham
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
va hai » van hai, va khai, va bai
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: te sac ky nang x hoi. lieu ((va hai) OR (va chai)) duc va thanh pho ((cua triet) OR (su triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang x hoi. lieu ((va hai) OR (va chai)) duc va thanh pho ((cua triet) or (su triet))~".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang x hoi. lieu ((va hai) OR (va chai)) duc va thanh pho ((cua triet) or (su triet))*.
