The signature document of the post bar, if legal and harmonious, will generally pass, about 24 hours later. Of course, this is the time stipulated by the system, but there is no airtight wall. There is a loophole in the approval of this signature document. You can try to drill it. For example, if you submit it before 1 12 in the afternoon, you may find that your signature file has been approved the next morning. Whether it can be passed depends on what your signature document is.
