Designs of e+e- colliders from the Z-pole and above are introduced. Their basic schemes, partial double ring (CEPC) and full double ring (FCC-ee), bring several important differences on the performance. On the other hand, there are a number of similarities in both designs, such as the crab-waist scheme, crossing angle, optimization of the dynamic aperture, etc. A very naive discussion will be presented based on an old idea to explore the possibility of circular colliders beyond the usual limit given by synchrotron radiation.
