Seriously. It is important to train contacts to sign on their behalf. Introducers should sign their own names in principle, but they really can't sign their own names for other special reasons. After a certain procedure, the person approved by the party organization can sign on his/her behalf. Joining the party is very strict. You must apply in person and have the introduction of the party introducer. Party organizations meet the standards of party member, and only after the approval of the branch general general party membership meeting can they become preparatory party member. As a party introducer, this is a glorious and serious issue, and it is not easy to find someone to sign it.
