  One widely-existed state --``harmony with diversity" in which individuals
freely express various viewpoints to sustain integration of social diversity,
but at the same time shared values ensure social coherence, can be considered
as the foundation of social diversity and coherence, however, which has never
attracted research attention. Its formation mechanism still remains unclear. To
address this issue, this study proposes an attraction-repulsion model based on
the general simple assumption that individuals tend to either reach an
agreement with shared opinions or to amplify difference from others with
distant opinions. It allows us to take account into the three core parameters:
interaction strength, individuals' susceptibility and tolerance to others'
opinions. We are concerned with the effect of not only time-varying topology
but also fixed interactions imposed by static social network, where the tasks
of heterogeneous individuals' attributes are also performed. Remarkably, the
simple model rules successfully generate the three above phases except for
fragmentation, along with three different transitions and the triple points. We
find that sufficient susceptibility, intermediate interaction strength and high
tolerance can benefit a balance between repulsive and attractive forces, and
thus the emergence of "harmony with diversity". However, fixed interactions can
introduce cluster-level self-reinforced mechanism which can unexpectedly
promote polarization. Heterogeneous susceptibility or tolerance turns out to be
an inhibiting factor, which should be avoided. A method to identify the phase
boundaries through computing the maximum susceptibility of entropy and stand
deviation of opinions, confirmed by numerical simulations, allows us to build
phase diagrams and to locate where the triple points are.
