In the baseline design, the circumference of CEPC will be taken as 50-70km. The single ring scheme and the partial double ring scheme are now both under study. In the single ring scheme, the electron and positron beam will share the beam pipes, thus a special orbit is needed to avoid the beam colliding at positions except the Interaction Points (IPs). While in the partial double ring scheme, the two beams will be separated into two beam pipes in the parasitic collision positions. This paper will show the latest design of the CEPC lattice, including both the pretzel and partial double ring scheme. Some critical issues that we encountered when designing the lattices will be discussed.
