摘要：

Instead of the popular gauge-dependent decomposition of the total angular momentum operator in QCD, we derived a gauge-invariant one with better classical correspondence. We also explored the possibility that the requirement of gauge invariance and classical correspondence will partly contradict with the commutation relationship of momentum and angular momentum.
