1. Explain that
   I recently discovered that the previously released version 15.0 software, after pojie, other functions can be used normally, but the Gantt chart cannot be used. This problem can be solved by applying a patch package. Now I will send the patch package to everyone.
   Note that this patch package is only for version 15.0.0, and version 15.0 released in the official account must be installed before use.
   
2. Obtain and
   send the 15.0 patch or 15.0 to the official account to obtain the patch package.
