Mobile stalls selling in-car music flash drives are no longer making money. It was a good business seven or eight years ago. At that time, not every family had a computer, and USB flash drives were expensive to sell. At that time, the mobile phone was still a non-intelligent machine or a Symbian machine, and the car did not have the function of Bluetooth. Now every family has a computer, the mobile phone can directly connect with Bluetooth to listen to music, and the USB flash drive is also the price of cabbage. Who will go to the stall to buy music?

A few years ago, this car music USB flash drive was, um, very profitable, and then this car music USB flash drive was all over the street, and then in recent years, this car music USB flash drive disappeared. How can we make money?

People use mobile phones to surf the Internet, so they make money, and now they make money.
