Query: Feasibility study of TPC at electron positron colliders at $Z$ pole
  operation   TPC is a promising technology for the future electron positron colliders.
However, its application might be limited at high event rate and high hit
occupancies. In this paper, we study the feasibility of using TPC at the
circular electron positron collider (CEPC) at $Z$ pole using full simulated $Z
\rightarrow q\bar{q}$ samples. By evaluating the local charge density and voxel
occupancy at different TPC parameters. Our study shows that the TPC could be
applied to the CEPC $Z$ pole operation if back flow ion is controlled to per
mille level. We also suggest the applicable TPC parameters for FCC-ee $Z$ pole
operations, whose instant luminosity is $2\times 10^{36}
\mathrm{cm^2\,s^{-1}}$, 2 orders of magnitude higher than that of CEPC.
