What poop in a hotel bathtub might imply

The media is abuzz with the news of Yan Chenglong, the winner of this year’s Xiangqi or Chinese chess tournament, being stripped of his title and banned for a year after it came to light that he had defecated in a hotel bath tub. What hasn’t got as much attention is, firstly, how exactly did this act come to light?  Secondly, what did the player have to say in his defence? Thirdly, what were the precise grounds/ formal charges that led to the title-stripping and the ban? 

According to a report in Global Times, after Yan checked out of the hotel, “a hotel employee found the bathtub in Yan’s hotel room was contaminated with excrement.” 

The report goes on to quote another agency on Yan’s response:

On Tuesday, Yan responded to the incident that he felt uncomfortable after drinking on December 17 and suffered from diarrhea. He failed to make it to the toilet in time and couldn’t help but defecating in the bathtub.

And this is what the Chinese Xiangqi Association has been quoted as saying about the incident:

Yan consumed alcohol with others in his room on the night of the 17th, and then he defecated in the bathtub of the room he was staying in on the 18th, in an act that damaged hotel property, violated public order and good morals, had a negative impact on the competition and the event of Xiangqi, and was of extremely bad character.
