Perhaps you should try some spelling variations:
hanh via » hanh vi, hanh va, anh va
cuu tre » cau tren, cau treo
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
cua tre » cua te, cua triet, dua tren
luc ban » cuc ban, luc bat, luc van
duc ban » duc tan, duc van, dua ban
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
va cam » va cham, va cac, va cao

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