Reborn Troops

"Wanwan, I heard that you are researching a new necklace that can protect the skin?" The customer's voice was full of curiosity.

Zhou Wanwan smiled and said, "Yes, but it's still in the research and development stage."

"I'm waiting. I trust the things in your store," said the customer.

After hanging up the phone, Zhou Wanwan felt a warm current in her heart. She looked at Qianqian and said, "We can't give up. We must make this thing."

Qianqian nodded: "Yes, let's work together."

The two began to get busy again. Zhou Wanwan was responsible for adjusting the circuit, and Qianqian was responsible for testing the material of the ball bearing.

Zhou Wanwan and Qianqian worked in the studio for several hours, but the problem with the heating device was still not solved. Zhou Wanwan decided to put down her work temporarily and called Master Zhongshan.

"Master Zhongshan, I'm Zhou Wanwan. I've encountered some technical difficulties here. I wonder if you have time to help me take a look?" There was a hint of anxiety in Zhou Wanwan's voice.

Master Zhongshan is a well-known jewelry designer in the industry and Zhou Wanwan's teacher. He gently replied: "Wanwan, what problem are you facing?"

Zhou Wanwan briefly described the problem with the heating device. Master Zhongshan pondered for a while and said, "How about this, I'll come over tomorrow morning and help you take a look."

"Really? Thank you so much!" Zhou Wanwan said excitedly.

The next morning, Master Zhongshan arrived as scheduled. He carefully checked the circuit and design of the heating device, and then said to Zhou Wanwan: "The problem lies in the sensitivity of the temperature sensor. You need a more accurate sensor to control the temperature."

Zhou Wanwan and Qianqian suddenly realized what was going on and quickly wrote down Master Zhongshan's suggestions. Master Zhongshan also taught them how to choose the right sensor and gave them some suggestions for improving the circuit.

After seeing off Master Zhongshan, Zhou Wanwan and Qianqian immediately started working on the new improvement. After a day of hard work, they finally solved the problem of the heating device.

"It should be fine now." Zhou Wanwan looked at the ball necklace in her hand with a satisfied smile on her face.

Qianqian also said excitedly: "Let's test it quickly."

The two connected the necklace to the mobile phone APP, adjusted it to the appropriate temperature, and then gently pressed the ball on the back of the hand. The ball was warm and comfortable, and the massage effect was also very good.

That day, Zhou Wanwan suddenly received a call from her old customer, Mrs. Li.

"Wanwan, I heard that your new necklace is ready?" Mrs. Li's voice was full of anticipation.

"Yes, Mrs. Li. We have just completed the test and the results are very good." Zhou Wanwan replied.

"That's great. I'll come and pick one up tomorrow." Mrs. Li said happily.

After hanging up the phone, Zhou Wanwan and Qianqian looked at each other, their hearts full of anticipation. They knew that this new necklace would become the star product of their store and attract more customers.

However, just as they were about to restart production, they encountered a new problem: the balls provided by the new supplier had a deviation in temperature control, resulting in the massage effect of the necklace not being as good as expected.

In Zhou Wanwan and Qianqian's shop, the launch of the new necklace should have been another peak in their careers, but the sudden problem was like a basin of cold water poured on their heads.

The two sat in the corner of the studio, brows furrowed, facing a pile of unqualified ball bearings on the table, their hearts heavy.

"Wanwan, we have to find a way to solve this problem." Qianqian broke the silence, her voice filled with unquestionable determination.

Zhou Wanwan nodded, with a firm light in her eyes: "Yes, we can't let our customers down. We must find a solution."

Just then, Zhou Wanwan's cell phone rang. It was Mrs. Li calling. She took a deep breath and answered the call.

"Wanwan, I just arrived at the store, why don't I see the new necklace?" Mrs. Li's voice was filled with a hint of confusion.

"Mrs. Li, I'm very sorry, we encountered some technical problems and the new necklace is temporarily unavailable." Zhou Wanwan tried her best to make her voice sound calm.

There was silence on the other end of the phone for a while, and then Mrs. Li said, "Wanwan, I believe in your ability. I am willing to wait until you solve the problem, and then I will come to pick it up."

After hanging up the phone, Zhou Wanwan and Qianqian smiled at each other. Mrs. Li's trust gave them great encouragement. They decided to find a solution to the problem no matter what.

In the next few days, the two ran around, looking for new suppliers and testing various ball bearings, but the results were not satisfactory.

Just when they were about to give up, Qianqian suddenly had an idea.

"Wanwan, why don't we design the ball bearings ourselves?" Qianqian's eyes sparkled with innovation.

Zhou Wanwan was stunned for a moment, then a smile appeared on her face: "Yes, we design and produce by ourselves, so we can fully control the quality."

The two took action immediately. They contacted a small processing factory and began to design a new ball roller. After countless trials and adjustments, a new ball roller was finally born. It not only has precise temperature control, but also has better massage effect.

When the first batch of new necklaces were completed, Zhou Wanwan and Qianqian were so excited that they almost jumped up. They immediately contacted Mrs. Li to tell her that the new necklaces were ready.

The next day, Mrs. Li came to the store. She picked up a new necklace and looked at it carefully.

"Wanwan, Qianqian, this is really perfect." Mrs. Li showed a satisfied smile on her face.

"Mrs. Li, this is something we made with great care. We hope you like it." Zhou Wanwan said with a smile.

Mrs. Li put on the necklace and felt the warmth and massage effect of the roller. She nodded repeatedly: "It's so comfortable. I will definitely recommend it to my friends."

With Mrs. Li's recommendation, the new necklace soon caused a sensation among customers. Zhou Wanwan and Qianqian's shop became lively again, with customers coming in an endless stream.
