The discovery of Higgs has inspired the idea of dedicated higgs factory of high energy electron-­‐positron collisions. Polarization can benefit the physics program not only as an efficient energy calibration, but lso suppress background signals. The experience from high energy electron beams at HERA and LEP has been encouraging, yet also exhibits the great difficulty. The aspect of reaching polarized beams at the beam energy of currently proposed electron-­‐positron collider based on S-­‐T polarization built-­‐up is daunting. Here, we present a scheme to achieve polarized electron and positron beam collisions at high energy.
