I am sorry for the trouble caused to you, because it is the first time that I have used such a platform, I am not proficient, and my English level needs to be improved. For example, I don't understand why the images written in the email can't be loaded in the community, and the data I pasted in the format will be reformatted. In the future, I will strengthen my description of the problem to avoid the efficiency problems caused by communication. Finally, my problem has been solved, thank you very much for your patience, thank you!
