Goodbye, Jiachen!

We will host the Goodbye Jiachen contest on January 27th from 1:00 PM to 6:00 PM (5 hours), featuring five problems.

The year 2024 marks the end of the Chinese lunar Jiachen Dragon Year, with Lunar New Year's Eve symbolizing its conclusion. The upcoming year will be the Yisi Snake Year, where the snake represents wisdom and the cycle of rebirth.

As time passes, UOJ continues to embrace new milestones. From Goodbye Jiawu to Goodbye Jiachen, we have witnessed UOJ's growth and transformation over the past decade.

This contest will take you into the world of Poker Kingdom. You will face challenges alongside five poker card characters, writing your own chapter of victory.
