Yin Yang Credit Blade Man

I was born in the Central Plains region, and since I can remember, my family has always traveled far and wide. It wasn't until I grew older that I realized that my grandfather, father, and uncles were what others called credit card holders. Later, in order to avoid going to school, when I was just ten years old, I became a credit card holder. I traveled tens of thousands of miles from south to north, east to west, and encountered some strange things. If you are interested, I can tell you and tell you what credit card holders are!
