The workshop is dedicated to bring together people interested in circular high energy e+e- collider (CEPC) as a Higgs factory as well as a future circular high energy pp collider (SPPC) beyond the Higgs factory. Participants will report on the progresses made in theory, accelerator design, detector design and optimization, simulations of benchmark physics processes etc. since the CEPC-SPPC kick-off meeting in September 2013. The focus will be on the preparation for the CEPC pre-CDR. International collaboration and study organization will also be examined.
