Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh va » thanh van, hanh va, thanh ha
va thanh » gia thanh, ban thanh, va tinh
cua tre » cua te, cuu tre, dua tren
sach ky » sac ky, sach y, sach kem
dang xa » dang xay, lang xa, dang ha
sach ty » sach y, sach tu, sach thu
co luc » coc luc, co luy
luc va » duc va, tuc va, loc va
va co » vo co

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ky) OR (sach ty)) dang xa hoi. lieu va co luc va thanh va ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sach ty)) dang xa hoi. lieu va co luc va thanh va ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) OR (sach ty)) dang xa hoi. lieu va co luc va thanh va ((cua tre) or (cua triet))".
• Adding a wildcard symbol may retrieve word variants: su ((sach ky) OR (sach ty)) dang xa hoi. lieu va co luc va thanh va ((cua tre) or (cua triet))*.
