Abstract: The light-front (LF) quark model based on the LF formalism and LF quantization of QCD provides a conceptually simple and phenomenologically feasible framework for researching the non-perturbative feature of hadrons, and has been extensively used to evaluate the form factor, decay constant and distribution amplitudes et al.. However, there still exist some debates about the self-consistency and covariance of the traditional LF quark models (the standard and the covariant LF quark model ). In this talk, it will be clearly shown that such two problems have the same origin, and might be resolved by using an improved correspondence scheme. Meanwhile, the well-known zero-mode effect will also be discussed.
