Perhaps you should try some spelling variations:
va triet » va thiet, va trien, ve triet
toc sac » toc sach, toc san, hoc sach
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
cam luc » cam xuc, cau luc
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
sac ky » cac ky, sai ky
va cam » va cham, va cac, va cao
luc va » duc va, tuc va, loc va
cua te » cua tu

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: toc sac ky nang xa hoi. hieu va cam luc va danh vi ((cua te) OR (va triet))~.
• Adding a wildcard symbol may retrieve word variants: toc sac ky nang xa hoi. hieu va cam luc va danh vi ((cua te) or (va triet))*.
