Abstract: In this talk, after revisiting a 3D chaotic system, its more rich hidden dynamics that have not been found previously in the known literature are clearly revealed, mainly for its singular orbits ( such as singular degenerate heteroclinic cycle, heteroclinic orbit,etc) and the dynamics at infinity. Especially, its Hopf bifurcation, zero-Hopf bifurcation and degenerate fold bifurcation, etc, at the origin, are in detail discussed. Meanwhile, numerical simulations not only support all obtained analytical results, but also further illustrate other new dynamical behaviors, including two heteroclinic orbits and their bifurcated chaotic attractors, infinite many singularly degenerate heteroclinic cycles with two-scroll and three-scroll chaotic ttractors near them.
