Don't Take My Identity Seriously

My name is Qian Ming and I am a traveling doctor, but this is not my main profession. It is just one of the identities I use when traveling around. If the situation requires, I will take off this vest and enter the next identity. Of course, if you want to move freely, you still need a little money and a reasonable identity. "As for why I often use the identity of Doctor You?" "Ahem, that's of course more convenient! This status is very popular in the eyes of others, and the most important thing is that you don't have to pay for traveling with a group. Why pay when you can get it for free?"
