How to persuade strangers to take pictures of themselves when traveling?

Just say it directly, there is no need to be tactful. But if you are the kind of person who keeps taking pictures, you should prevent strangers from getting bored. For example, I don't like taking pictures of others, and I don't like taking pictures myself. In this case, you should be measured and take fewer pictures. Remember to thank you after taking pictures and add two compliments: your composition is so strange, I like it. This picture is beautiful, thank you. Wait, wait, wait
