Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
va dinh » van dinh, va kinh, va tinh
cua tre » cua te, cuu tre, dua tren
va hanh » van hanh, va thanh, va danh
hieu va » lieu va, hieu qua
cam luc » cam xuc, cau luc
nang xa » nang x, lang xa, nang ma
sac ky » cac ky, sai ky
va cam » va cham, va cac, va cao
te sac » te sach, te cac, te san

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 xa hoi. hieu va cam luc ((va hanh) OR (va dinh)) vi ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. hieu va cam luc ((va hanh) or (va dinh)) vi ((cua tre) OR (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. hieu va cam luc ((va hanh) or (va dinh)) vi ((cua tre) OR (cua triet))*.
