  Abstract: 

  Lattice QCD is an ab initio approach of solving QCD problems with both the statistical and systematic uncertainties under control. One of its important applications is to study the nucleon structures, which promotes our understanding to the building block of the visible universe. I will introduce two of our recent calculations using the overlap type of fermion discretization as examples. The first one is the quark spin contribution to the total nucleon spin and the second one is the nucleon mass decomposition. Experimentally, they are closely related to the future EicC.
