Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
vanh dai » van dai, vanh tai, lanh dao
tu sach » thu sach, su sach, te sach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, mang xa
nang ma » tang ma, sang ma, nang cao
qua cam » qua cham, qua cac, qua ca
va vanh » va van, va danh, va hanh
xuc va » duc va, tuc va, luc va

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((nang xa) OR (nang ma)) hoi. hieu qua cam xuc va vanh dai cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu sach ky ((nang xa) OR (nang ma)) hoi. hieu qua cam xuc va vanh dai cua triet*.
