Query: Glue Spin of the Proton   We report the progress on the lattice QCD calculation of the glue spin
contribution to proton spin. This calculation is carried out with valence
overlap fermion on 2+1 flavor DWF gauge configurations at two lattice spacings
with the momentum of the frame in the kinematic range $0\leq p^2 \leq 2$
GeV$^2$. A mild frame dependence is observed. The matching and mixing with
large-momentum effective field theory are in progress. The unrenormalized
result at $p^2=4$ GeV$^2$ with $O(a^2)$ correction gives $S_G$ = 0.13(3).
