Perhaps you should try some spelling variations:
ban chinh » lan chinh, van chinh, hanh chinh
nang xa » nang x, lang xa, nang ma
ve cham » va cham, ve chat, vu cham
cuc ban » cua ban, cac ban, cuu ban
cua tre » cua te, cuu tre, cua triet
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cam » ve cac, va cam, ve cau
ve cai » va cai, ve cac, ve tai

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 sac ky nang xa hoi. hieu ((((ve cam) OR (ve cai))) OR (ve cham)) cuc ban chinh tri cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu ((((ve cam) OR (ve cai))) or (ve cham)) cuc ban chinh tri cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu ((((ve cam) OR (ve cai))) or (ve cham)) cuc ban chinh tri cua tre*.
