  The emergent universe scenario provides a possible alternative to bouncing
cosmology to avoid the Big Bang singularity problem. In this paper we study the
realization of the emergent universe scenario by making use of Quintom matter
with an equation of state across the cosmological constant boundary. We will
show explicitly the analytic and numerical solutions of emergent universe in
two Quintom models, which are a phenomenological fluid and a nonconventional
spinor field, respectively.
