Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van hanh » van thanh, ban hanh, van anh
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
qua cac » cua cac
cac xuc » cam xuc, cac nuoc, chat xuc
va hanh » va thanh, va danh, ban hanh
su tien » su kien, su hien, tu tieng
vu sac » vu sach, vu san, va sac
sac ky » cac ky, sai ky

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: vu sac ky lang xa hoi. hieu qua cac xuc ((va hanh) OR (van hanh)) vi ((cua triet) OR (su tien))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky lang xa hoi. hieu qua cac xuc ((va hanh) OR (van hanh)) vi ((cua triet) or (su tien))~".
• Adding a wildcard symbol may retrieve word variants: vu sac ky lang xa hoi. hieu qua cac xuc ((va hanh) OR (van hanh)) vi ((cua triet) or (su tien))*.
