If the lawyer is changed in the middle of a criminal case, if the lawyer goes to meet before, will it lead the client in a bad direction, and is it illegal?

In a criminal case, the lawyer was changed. If the lawyer goes to see him before, it will lead the client in a bad direction of breaking the law. If a lawyer is changed in the middle of a criminal case, the original lawyer may not meet or contact the client again without the consent of the client. If the original lawyer still meets the client after leaving the case and tries to guide the client to make a bad decision, this behavior may constitute the crime of embezzlement, bribery, suspected interference with judicial behavior and so on. Therefore, it is illegal to change lawyers in the middle of a criminal case, and to lead the client in a bad direction if the lawyers meet before.
