Perhaps you should try some spelling variations:
cau phuc » cau truc, chau phu, huu phuc
dang xay » dang van, van xay
tu sach » thu sach, su sach, te sach
va danh » va dinh, va dan, dia danh
sach ky » sac ky, sach y, sach ty
va hanh » van hanh, va thanh, ban hanh
qua cau » quan cau, qua cac, qua ca
xay hoi » xa hoi, tay hoi, cay phoi
ky dang » ky nang, ky danh
cua tuc » cua duc, cua tu, cua thuoc
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky dang xay hoi. hieu qua cau phuc ((va hanh) OR (va danh)) vi ((cua te) or (cua tuc))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky dang xay hoi. hieu qua cau phuc ((va hanh) OR (va danh)) vi ((cua te) OR (cua tuc))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky dang xay hoi. hieu qua cau phuc ((va hanh) OR (va danh)) vi ((cua te) or (cua tuc))*".
