  I review hadronic processes involving strange hadrons, especially hyperons
from the quark structure point of view. The strong interaction of quarks
expects several important new features when the strangeness is introduced upon
the non-strange degrees of freedom. I concentrate on the instanton induced
interaction, effects of the Pauli principle for strangeness and the nonleptonic
weak interaction of strangeness. The single hadron as well as the two baryon
systems including the $H$ dibaryon and other exotic hadronic systems with
strangeness are studied in this context.
