Recently, Qieke has been very unstable. Although there are many complaints, people still can't give it up - it's a love-hate relationship. My intuition is that Qieke is going through a tough time. Based on my limited knowledge, it seems like Qieke is upgrading or replacing the backend program.
I hope Qieke will stabilize soon. To quote a classic line from Zi Xia: even when it crashes, it does so in such a stylish way!
