The 2014 ACM-ICPC Asia Xian Regional Contest (2014) takes place on 25 Oct 2014 - 26 Oct 2014. It was hosted by Northwestern Polytechnical University in Xi'an, China. Tasks were set by Fudan University this year. Time limits and memory limits are slightly different from onsite contest due to some mysterious behaviour of Codeforces judging machines.
Virtual contest is a way to take part in past contest, as close as possible to participation on time. It is supported only ICPC mode for virtual contests.
