Perhaps you should try some spelling variations:
cau phuc » cau truc, chau phu, huu phuc
va triet » va thiet, va trien, ve triet
su sach » so sach, vu sach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
cau luc » cau truc
va hanh » van hanh, va thanh, va danh
vi va » vi van, vai va, vu 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: su sach ky nang xa hoi. hieu qua ((cau luc) OR (cau phuc)) va hanh vi va triet~.
• Adding a wildcard symbol may retrieve word variants: su sach ky nang xa hoi. hieu qua ((cau luc) or (cau phuc)) va hanh vi va triet*.
