The "partner split" incident has intensified. What happened to Deyun Society?

Some time ago, Deyun Society officially released an announcement with a list of members. The eagle-eyed audience found that Qin Xiaoxian, Sun Jiuxiang, He Jiuhua and Shang Jiuxi, who were originally good partners, were separated one after another, and the way several people partnered was a little confusing, so things got worse and worse. Finally, even Degang Guo came out to preside over the overall situation.
