  According to the fundamental idea that a steering inequality can be
constructed by just considering the measurements performed by Bob, and from the
definitions of steering from Alice to Bob, a general scheme for designing two
different kinds of linear steering inequalities (LSIs) is developed to detect
the two-way steerability for bipartite system and the genuine multipartite
two-way steerability for multipartite system, respectively. Besides the LSIs
constructed from the known one-way criteria and the Bell operators, several
other types of LSIs are also considered.
