This contest is prepared by Zhejiang University, which has already been used as the The 47th ICPC Asia Hong Kong Regional Contest. There are 127 teams participating in the Regional. This contest also serves as Day 3 in 2023 Winter Petrozabodsk Camp on Feruary 2nd, 2023.

The contest will start soon. You can participate in the contest in the following three time windows:
