CP violation in lepton sector and mass hierarchy are two among unsolved questions in neutrino physics. In this presentation, we will explore a potential to discover CP violation and mass hierarchy with a joint analysis of T2K-II, NOvA and JUNO experiments. T2K (located in Japan) and NOvA (located in USA) are two world-leading accelerator-based long baseline neutrino oscillation experiments. T2K-II is an extension of the T2K experiment which can provide a strong evidence for CP violation. NOvA is significantly sensitive to both CP violation and mass hierarchy. JUNO, a medium baseline reactor neutrino experiment which is under construction in China, is able to have 3 $\sigma$ or higher sensitivity to the mass hierarchy and can achieve better than $1\%$ precision on solar parameters with its proposed running in six years. A combined analysis of T2K-II, NOvA and JUNO at the end of their runs can completely establish the neutrino mass hierarchy and indicate CP violation in the lepton sector at more than $4 \sigma$ if $\delta_{CP} ~ -\pi/2$.
