The dynamics of repeating fast radio bursts (FRBs) are driven by their physical nature and central engine, however their event rate, energy distribution and temporal occurrence behaviour are still remain uncertain due to the server lack of information of bursts. Recently, the available of high-frequency observation data for the Five-hundred-meter Aperture Spherical radio Telescope (FAST) has made it possible to statistically study the temporal occurrence on timescales from several milliseconds to over several thousand seconds. In this research we studied both the FRB121102 and FRB20201124A temporal occurrence and report here a statistical result about the behaviour of the waiting time (or recurrence-time) between successive bursts. The results exhibit novel scaling and universality which have not reported in the field yet. Specifically, we find the scaling law for FRBs recurrence-time distribution which is a clear indication of the importance of correlations in the structure of its physical nature and central engine. The scaling relationships were observed for time scales spanning three orders of magnitude. Given that they are sharing the same scaling law between two repeating FRBs, we infer that the scaling law of waiting time distribution should acts as a indicator which provides insights into the physical nature and the development of the central engine model.
