Perhaps you should try some spelling variations:
cua tre » cua te, cuu tre, cua triet
danh vi » hanh vi, dinh vi, danh di
va danh » va dinh, va dan, va hanh
tu cham » toc cham, thi cham
ve cham » va cham, ve chat, vu cham
xay hoi » tay hoi, cay phoi, gay thoi
ky dang » ky nang, ky danh
sac ky » cac ky, sai ky
vi cua » vai cua, di cua
tu sac » tu sach, tu cac, tu 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: tu sac ky dang ((xay hoi) OR (xa hoi)). hieu ((ve cham) OR (tu cham)) hoc va danh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky dang ((xay hoi) OR (xa hoi)). hieu ((ve cham) or (tu cham)) hoc va danh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky dang ((xay hoi) OR (xa hoi)). hieu ((ve cham) or (tu cham)) hoc va danh vi cua tre*.
