To decipher the mechanism of high temperature superconductivity(SC),it is important to know how the superconducting pairing emerges from the unusual normal states of cuprate superconductors,including pseudogap,anomalous Fermi liquid and strange metal(SM).A long-standing issue under debate is how the superconducting pairing is formed and condensed in the SM phase because the superconducting transition temperature is the highest in this phase.
