Perhaps you should try some spelling variations:
ve triet » va trien, su triet
cau phuc » cau truc, chau phu, huu phuc
nang xay » dang xay, nganh xay, nang xuan
va hanh » van hanh, va thanh, va danh
cau luc » cau truc
sach ky » sach y, sach ty, sach kem
xay hoi » xa hoi, tay hoi, cay phoi
sac ky » cac ky, sai ky
vi ve » va ve, gi ve, ve ve

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: vu ((sach ky) OR (sac ky)) nang xay hoi. hieu qua ((cau luc) OR (cau phuc)) va hanh vi ve triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sach ky) OR (sac ky)) nang xay hoi. hieu qua ((cau luc) or (cau phuc)) va hanh vi ve triet~".
• Adding a wildcard symbol may retrieve word variants: vu ((sach ky) OR (sac ky)) nang xay hoi. hieu qua ((cau luc) or (cau phuc)) va hanh vi ve triet*.
