Perhaps you should try some spelling variations:
cua triet » su triet, va triet
cua viet » ca viet, hoa viet, cua vat
cham xuc » cam xuc, chat xuc, cham soc
dang xay » dang van, van xay
danh lai » danh sai, gianh lai, dinh lam
va danh » va dinh, va dan, va hanh
so sach » so sanh, bo sach, co sach
sach ty » sach y, sach tu, sach thu
hieu va » lieu va, hieu qua
va cham » va chat, va tham
xuc va » duc va, tuc va, luc 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: so sach ty ((nang x) OR (dang xay)) hoi. hieu va cham xuc va danh lai ((cua triet) OR (cua viet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty ((nang x) or (dang xay)) hoi. hieu va cham xuc va danh lai ((cua triet) OR (cua viet))~".
• Adding a wildcard symbol may retrieve word variants: so sach ty ((nang x) or (dang xay)) hoi. hieu va cham xuc va danh lai ((cua triet) OR (cua viet))*.
