Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
truc va » thuc va, thuc vat, trung va
dan vai » dan va, dan tai, dan vat
su sach » so sach, vu sach
sach ky » sac ky, sach y, sach ty
dang xa » dang xay, lang xa, dang ha
ky dang » ky nang, ky danh
tuc va » thuc va, tuc xa, duc va

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 sach ky dang xa hoi. lieu va cac ((tuc va) OR (truc va)) dan vai ((cua triet) OR (su triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky dang xa hoi. lieu va cac ((tuc va) OR (truc va)) dan vai ((cua triet) or (su triet))~".
• Adding a wildcard symbol may retrieve word variants: su sach ky dang xa hoi. lieu va cac ((tuc va) OR (truc va)) dan vai ((cua triet) or (su triet))*.
