In this talk, I will first introduce conformal anomaly corrections on the black hole geometry in 4d spherical symmetric spacetime. After introducing the black hole solution, I will discuss dynamical and thermodynamical aspects of this black hole. For dynamical aspect, we use massive particle motions  as probes to investigate the effect of conformal anomaly. We find that conformal anomaly will generally enhance the chaotic behavior of particle motions. For thermodynamical aspect, we investigate the phase transition and critical phenomena of this anomaly corrected black hole. Especially, we find that anomaly can trigger the violation of Rushbrook scaling law at the critical point. Our result provides the first example of such scaling law violation in four dimensional spacetime.
