Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
cac toc » cac toi, cac nuoc, cac thoi
ta hanh » ta thanh, va hanh, tu hanh
hanh va » hang va, hanh vi
cua tre » cua te, cuu tre, cua triet
su sac » su sach, su xac
su cac » tu cac, su cao, su can
toc ta » toc tay, toc thai
va cua » va chua, via cua, ca cua

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: ((su sac) OR (su cac)) ky nang xa hoi. lieu va cac toc ta hanh va cua tre~.
• Adding a wildcard symbol may retrieve word variants: ((su sac) or (su cac)) ky nang xa hoi. lieu va cac toc ta hanh va cua tre*.
