Abstract
Lattice QCD provides a genuine non-perturbative way to solving QCD, the fundamental theory of quarks and gluons. It plays an important role in the high-intensity frontier and precision flavor physics.
High precision requires the development of new ideas and methods in the lattice QCD calculation. In this talk, I will discuss our recent work on the calculation of hadron-mass splitting, neutrinoless double beta decay, pion charge radius and rare kaon decays.
