报告摘要：Unlike the simple picture shown by the quark model, the origin of the proton mass and spin based on the related experiments results are pretty complicated and challenge our understanding of the QCD physics at the non-perturbative region. I should show our recent lattice QCD results on the decomposition of this two quantities and how important of the gluon components are.
