Photographers and tourists take pictures.

As a college student, it's good to do part-time jobs to earn money.

Several people in the park here are taking pictures of tourists with ordinary cameras, each 15 yuan. When they deal with the park, they will put a printer in the corner and print the photos to the tourists immediately with photographic paper. After talking to them, they said it was better than work ... you can also bring a printer and battery to print on the spot, and there is that polaroid camera that can produce films directly (with high cost). Think about it yourself.
