If you sign for it yourself, please sign in the "Signature of Recipient" column, show your ID card, and fill in the ID number at the back of your signature. If it is on behalf of the signer, then sign your name (your name, not the name of the recipient) in the column of "on behalf of the signer" and fill in the ID number. Finally, fill in the receipt time, and if necessary, indicate in the "Remarks" column below that you signed for others. I hope my answer can help you o(∩_∩)o ... haha.
