Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
vuc nang » cuc nang, vu nang, chuc nang
chat duc » chat xuc, chat doc, chet duoc
ve chat » va chat, van chat
cua tre » cua te, cuu tre, dua tren
danh vi » hanh vi, dinh vi, danh di
va danh » va dinh, va dan, va hanh
te sach » toc sach
hieu ve » hieu va, hieu van
v nang » va nang, vu nang, van nang

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: te sach ((v nang) OR (vuc nang)) xa hoi. hieu ve chat duc va danh vi ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((v nang) or (vuc nang)) xa hoi. hieu ve chat duc va danh vi ((cua tre) OR (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: te sach ((v nang) or (vuc nang)) xa hoi. hieu ve chat duc va danh vi ((cua tre) OR (cua triet))*.
