Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
va triet » va thiet, va trien, ve triet
hanh vai » hanh vi, hanh va, hanh tai
va hanh » van hanh, va thanh, va danh
cac xuc » cam xuc, cac nuoc, chat xuc
hieu ve » hieu va, hieu van
nang xa » lang xa, nang ma, mang xa
ve cac » va cac, vien cac
sai ky » sac ky
xuc va » duc va, tuc va, luc va
tu sai » tu bai, tu san, tu cai

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