Cheng Qian understood this principle and, after considering it in his mind, came up with a candidate.

The next day, Yu Yin and the others placed the sausages on the food counter of the department store, and also put up a promotional poster in a prominent place, making it easy to see.

"Sister Zhu, Manager Cheng should have told you that you get a one-cent commission for every sausage you sell. It's absolutely true. If you want to earn more money, sell more goods. You have more experience in that." Yu Yin spoke to the saleswoman introduced by her second brother-in-law. Her counter sold snacks.

"Understood, I know what to do. I'll handle the samples properly; I won't secretly take them back and prevent the employees from trying them." Sister Zhu has worked in the department store for many years and has a lot of experience. Moreover, she's related to Cheng Qian.

With everything ready, people streamed in as soon as the building opened for business, most drawn by the promotional posters. Sister Zhu was very helpful, providing detailed explanations and patiently guiding customers through the tastings; many bought some after trying them.

Yu Yin and the others didn't stay long and left after a short while.

"Sister Yu Yin, after the sales figures for the building over the next three days are released, I'm going to move on to other department stores and supply and marketing cooperatives." Zhong Liang is now feeling that he doesn't have enough people; he's desperately short-staffed.

"Okay, hurry up and recruit people. Once they're in place, you don't need to do sales anymore. There are more important things to do."

Yu Yin didn't want her deputy factory director to be running around doing business every day.

A week later, many people knew the name of the ham sausage and tasted it. The ham sausage became famous!
