"Then you..." Zhou Min wanted to ask something else.

Ji Wanmei changed the subject: "By the way, do you have time this afternoon to go to the store with me? I'm planning to start the trial operation this afternoon, and I might be too busy. Could you come and lend me a hand?"

“Sure, I’d love to see what you got out of your trip to Guangzhou.”

The topic was dropped, but Ji Wanmei realized how serious her father was about it.

Since he's come to Zhou Min, he's probably going to see Lu Zhuoxuan too.

Ji Wanmei is going to learn Shu embroidery from Grandma Song. Besides her classmates and roommates, she will probably run into Lu Zhuoxuan the most.

After Ji Wanmei and Zhou Min finished getting ready, they went to the food street outside the school for a bite to eat, and then went to the audio-visual store.

The original landlord ran a bookstore called "Shidai Bookstore". Ji Wanmei thought the name was good, so she simply changed the suffix and called it "Shidai Audio-Visual Store". She took down the landlord's store sign and put it in the back warehouse.

The store started its trial operation in the afternoon. Tens of thousands of people opened all four doors of the L-shaped store and put a small blackboard with "Trial Operation" written on it at the entrance.

Students passing by saw that the music and video store had opened and began to enter one after another.

Ji Wanmei's original business plan was to allow students to rent CDs and cassettes with their student IDs. CDs would cost one yuan per day to rent, while cassettes were cheaper, costing only fifty cents.

If sold directly, a disc is nine yuan, and a cassette tape is five yuan.

This price is the official price.

For ordinary students, it would naturally be too expensive, so they would prefer to rent, which is more cost-effective. After all, a disc or a cassette tape, if you spend a day listening to or watching it, only costs 50 cents or 1 yuan to return it, which is not very expensive. Even students with limited living expenses can afford to rent it if they save a little.

However, during the trial operation, after registering and renting out a dozen or so discs, Ji Wanmei discovered a problem.

The mechanism she originally proposed, which required registration and rental based on student ID, was somewhat unscientific.

A student ID doesn't necessarily mean the person is the actual owner. And if someone with poor manners rents her discs based solely on a student ID and then doesn't return them, she'll lose the cost of the discs for nothing.

Zhou Min was looking around with great curiosity at the movie DVDs, music tapes, and vinyl records on Ji Wanmei's shelf.

She had never even seen these things before.

Ji Wanmei leaned on the shopkeeper's table by the door, deep in thought. She turned to Zhou Min and said, "This won't work. I need to think of another way to improve this spy rental model."
