The contract application failed, and people said that my book did not meet the contract criteria! I wrote a comment as soon as I saw it, but people said that it was under review and was not allowed to send it! After a while, the computer inexplicably crashed automatically, and as soon as I killed the virus, several viruses hung up...... Is this a coincidence or what? My book isn't worth it...... I'll just take it as a coincidence!
