You can entrust other institutions to handle it.
China Patent Examination South stipulates that the same applicant or patentee has signed a general power of attorney for multiple applications or patents and patent agencies, and patent agencies can submit the general power of attorney to the Patent Office for filing. After examining the original power of attorney submitted by the patent agency, the Patent Office gives the record number of the power of attorney and puts the original power of attorney on record. When applying for a case, an agency may submit a copy of the general power of attorney after filing, which has the same legal effect as the original.
In other words, the power of attorney is used to prove that the patent agency is qualified to handle your company's business and is not binding on your company. You can entrust other institutions to handle it.
I hope the answer will help you.
