How should the host ask for help to move things during the meeting?

Just reply that it is my responsibility to help you move things. Because helping others will make you feel happy inside, and you will certainly become more friendly in the future. When the other party says that you will help me move things, it means that you have an inherent requirement for yourself and should actively cooperate with the other party. Only when you have frank communication and understanding with each other can two people consider each other everywhere in their lives.
