After seeing the client at the trial stage, can the lawyer tell him all the information the client told him?

From your point of view, the principal and the principal are not the same person. Generally speaking, the client is a close relative of the client. After the lawyer met with the client, what did the client say, whether the lawyer informed the client that this was the lawyer's right, and some facts related to the progress of the case. If the disclosure will have adverse consequences for the client, it is not against the law and professional ethics for the lawyer not to tell the client. If you tell, the lawyer should also consider it, because some parties will let the lawyer take a message. If the content of the message is to ask the parties to find someone to commit perjury and other things that hinder judicial justice, lawyers as messengers are likely to be investigated for criminal responsibility. Therefore, I personally think that it is a lawyer's basic right to selectively transmit information.
