Hi Codeforces, We are the judges of the icpc Shanghai regional contest coming this weekend. As contests are held online this year, we have more teams attending the contest and less teams that are available for testing the problems. So we are looking for non Chinese teams (or Chinese teams if your school will not attend the regional this weekend) who volunteer to test the problem set. We just need 15 redhours (3 red people competing for 5 hours together). If you are interested, please don't hesistate and message me!
