Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
so sach » so sanh, bo sach, co sach
sach ky » sac ky, sach y, sach ty
ky dang » ky nang, ky danh
dang xa » dang xay, lang xa, dang ha
nam xuc » nam xua, nam thuc, nam duoc
va hanh » van hanh, va thanh, va danh
hanh va » hang va, hanh vi
cuu tre » cua tre, cau tren, cau treo

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

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