Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
va hanh » van hanh, va thanh, va danh
thuc va » thuc vat, thuc dan, thuc day
so sach » so sanh, bo sach, co sach
nang ma » tang ma, sang ma, nang cao
qua cam » qua cham, qua cac, qua cai
y nang » ky nang, ly nang, v nang
ma hoi » mai hoi, xa hoi, ma hoa
qua ca » qua cac, qua cua, qua cai

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 y nang ma hoi. hieu ((qua cam) OR (qua ca)) thuc va hanh vi ((cua triet) OR (su triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach y nang ma hoi. hieu ((qua cam) OR (qua ca)) thuc va hanh vi ((cua triet) or (su triet))~".
• Adding a wildcard symbol may retrieve word variants: so sach y nang ma hoi. hieu ((qua cam) OR (qua ca)) thuc va hanh vi ((cua triet) or (su triet))*.
