Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
sach ky » sach y, sach ty, sach kem
va cham » va chat, va tham
xuc ban » cuc ban, quoc ban, xuat ban
duc ban » duc tan, duc van, dua ban
sac ky » cac ky, sai ky
x hoi » xa hoi, o hoi, x ho
d cua » de cua, do cua, da cua

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 ((sach ky) OR (sac ky)) nang x hoi. lieu va cham ((xuc ban) OR (duc ban)) anh d cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sac ky)) nang x hoi. lieu va cham ((xuc ban) OR (duc ban)) anh d cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) or (sac ky)) nang x hoi. lieu va cham ((xuc ban) OR (duc ban)) anh d cua triet*.
