  We estimate the impact of asymmetry measurements of Deeply Virtual Compton
Scattering (DVCS) with transversely polarized proton beam taken at a future
Electron Ion Collider in China (EicC) on the extraction of Compton Form Factors
(CFFs). The CFFs extracted from an analysis based on artificial neural-network
approach are reweighted by means of pseudo-data generated in the expected
kinematic region of EicC. We find a remarkable improvement in the extraction of
CFF $\textbf{Im} {\mathcal E}$, especially at the range of parton momentum
fraction $x \sim$ 0.01, thus hinting for a future experimental probe of the
parton orbital angular momentum. This work casts a glance at a practical
implementation of Bayesian reweighting method on CFFs' impact study.
