After the reactor angle $\theta_{13}$ was measured by Daya Bay and RENO in 2012, neutrino physics has been entering a new era of precision measurement. The next generation of neutrino experiments would measure the leptonic Dirac CP phase precisely, in addition to the octant of the atmospheric angle $\theta_{23}$ and the neutrino mass hierarchy. Nevertheless, precision measurement of neutrino oscillation parameters is not enough for identifying the underlying theory behind neutrino oscillation. Turning neutrino oscillation experiment into neutrino collider can help us to get more insight into the new physics of the neutrino sector. In this talk I would first briefly review the current status of neutrino oscillation and then introduce how to turn neutrino experiments into neutrino collider.
