20240609-The new hard disk has been replaced, and the original server has been replaced. The machine can bear the high load of our site, but because some details of the optimization last year were a long time ago, I forgot how to set them up. Now there are hundreds of thousands of links bursting out in large quantities, which may also cause 500 errors to appear frequently. Please use it for now. The optimization will be carried out gradually until it returns to the previous good state. In addition, the HR system is temporarily closed due to frequent reading and writing. If there are any other bugs, you can give feedback in the forum and keep it.
