It is strongly indicated that, unlike all the other cuprate superconductors, the superconductivity of Pr247, which is composed of Pr123 and Pr124, is driven by Cu2O2 double chains. Here, through the Cu nuclear-spins, we report the electronic states of superconducting Pr247 and three-axis oriented Y124.
