Perhaps you should try some spelling variations:
nuoc sach » nguoi sach, hoc sach, cuoc cach
cua triet » su triet, va triet
thanh vi » hanh vi, thanh va, thanh ve
va thanh » gia thanh, ban thanh, va tinh
cua viet » ca viet, hoa viet, cua vat
cac khoi » cac thoi, cac khoan, cach thoi
hieu va » lieu va, hieu qua
cao xuc » cam xuc, cao duc, cao suc
y nang » ky nang, ly nang, v nang
xuc va » duc va, tuc va, luc va
va cao » va cac, va co, va dao

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: nuoc sach y nang ((xa hoi) OR (cac khoi)). hieu va cao xuc va thanh vi ((cua triet) OR (cua viet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc sach y nang ((xa hoi) or (cac khoi)). hieu va cao xuc va thanh vi ((cua triet) OR (cua viet))~".
• Adding a wildcard symbol may retrieve word variants: nuoc sach y nang ((xa hoi) or (cac khoi)). hieu va cao xuc va thanh vi ((cua triet) OR (cua viet))*.
