  The relevance of chiral symmetry in baryons is highlighted in three examples
in the nucleon spectroscopy and structure. The first one is the importance of
chiral dynamics in understanding the Roper resonance. The second one is the
role of chiral symmetry in the lattice calculation of $\pi N \sigma$ term and
strangeness. The third one is the role of chiral $U(1)$ anomaly in the
anomalous Ward identity in evaluating the quark spin and the quark orbital
angular momentum. Finally, the chiral effective theory for baryons is
discussed.
