I have a document to be signed by the leader, but I don't know where to sign it. What should I do?
General conventional documents, the leader knows where to sign, just give it to him. If it's a foreign document and you're worried that the leader doesn't know it, you can call the other party to ask where to sign it, draw the signature place with a pencil, and click it a little when you give it to the boss, so as to avoid confusion and waste of time.
