  Recently quantum nonlocality has been classified into three distinct types:
quantum entanglement, Einstein-Podolsky-Rosen steering, and Bell's nonlocality.
Among which, Bell's nonlocality is the strongest type. Bell's nonlocality for
quantum states is usually detected by violation of some Bell's inequalities,
such as Clause-Horne-Shimony-Holt inequality for two qubits. Steering is a
manifestation of nonlocality intermediate between entanglement and Bell's
nonlocality. This peculiar feature has led to a curious quantum phenomenon, the
one-way Einstein-Podolsky-Rosen steering. The one-way steering was an important
open question presented in 2007, and positively answered in 2014 by Bowles
\emph{et al.}, who presented a simple class of one-way steerable states in a
two-qubit system with at least thirteen projective measurements. The inspiring
result for the first time theoretically confirms quantum nonlocality can be
fundamentally asymmetric. Here, we propose another curious quantum phenomenon:
Bell nonlocal states can be constructed from some steerable states. This novel
finding not only offers a distinctive way to study Bell's nonlocality without
Bell's inequality but with steering inequality, but also may avoid locality
loophole in Bell's tests and make Bell's nonlocality easier for demonstration.
Furthermore, a nine-setting steering inequality has also been presented for
developing more efficient one-way steering and detecting some Bell nonlocal
states.
