Signing is to pay legal responsibility, and at the same time, it is necessary to indicate whether you agree or disagree, and there must be a clear personal reply.

In terms of contracts, there are both "signatures" and "signatures", but they generally need to be signed. And "signature" is a general term, including "signature". So "signature" is not necessarily "signature", but also "instruction", such as consent, compliance, permission to implement and so on.
