Shen Tingzhou took the cloth bag, opened it, and saw that it contained several white steamed buns and a small dish of pickled vegetables. His heart stirred slightly, and his gaze towards Old Madam Shen softened a little. Since Lin Wanqiu's public confrontation with her awful in-laws, Old Madam Shen, although still not exactly close to her, had toned it down considerably and would occasionally help take care of Nian'an.

"Thank you, Mom," Shen Tingzhou said.

Lin Wanqiu also stood up and smiled at Grandma Shen: "Mom, thank you for your hard work. Come in and sit for a while."

Grandma Shen waved her hand: "No, I'll just stand here for a while. Nian'an, don't cause your parents any trouble."

Shen Nian'an nodded obediently, but his eyes were drawn to the colorful products on the display stand. He broke free from Lin Wanqiu's embrace and ran to the stand, curiously examining the small steamed buns and pastries: "Mommy, did you make all of these? They look so beautiful!"

"Yes, Mom made them all." Lin Wanqiu smiled and patted his head. "Nian'an, would you like to try some?"

Shen Nian'an nodded vigorously, and Lin Wanqiu picked up a small pumpkin-flavored steamed bun and handed it to her. He carefully took it, took a small bite, and the sweet taste melted in his mouth. He immediately showed a satisfied smile: "Delicious! Mom's cooking is so delicious!"

Looking at her son's adorable face, Lin Wanqiu was filled with happiness. She picked up a nut energy bar and handed it to Shen Nian'an: "Try this too, it'll give you some energy."

Shen Nian'an took the energy bar and ate it in small bites, his eyes constantly observing the situation in front of the booth. He saw his mother busy introducing products to customers, and his father busy weighing and packing, both busy but with smiles on their faces. He also saw some customers buying a lot of products, while others were carefully inquiring about the ingredients and prices.

"Mom, how much is one of these?" Shen Nian'an asked, pointing to a small fruit and vegetable bun.

Lin Wanqiu patiently replied, "These small steamed buns cost one cent for five."

Shen Nian'an tilted her head and started calculating seriously: "Ten of them would be two cents, and one hundred would be two dollars?"

Lin Wanqiu looked at her son with some surprise; she hadn't expected Nian'an to be able to calculate the result so quickly. Shen Tingzhou also noticed this, a hint of satisfaction flashing in his eyes: "Nian'an is really smart; he can even figure this out."

Chen Nian'an was even happier to receive the praise. He continued, "Mom, what about this yam and lotus seed cake? How much does it cost per pound?"

"A pound of yam and lotus seed cake costs eight cents," Lin Wanqiu said.

"So if I buy two jin, it'll be one yuan and six jiao, right?" Shen Nian'an asked again.

Lin Wanqiu nodded, secretly delighted. Nian'an was only four years old, yet she possessed such remarkable mathematical talent; this greatly surprised her.

Just then, a customer walked over and wanted to buy three jin (1.5 kg) of nut energy bars. One jin of nut energy bars cost one yuan and twenty cents. Lin Wanqiu was about to calculate the price when Shen Nian'an spoke up first, "Auntie, three jin is three yuan and sixty cents!"

The customer looked at Chen Nian'an in surprise: "Little guy, you're amazing! You calculated so fast!"

Lin Wanqiu felt incredibly proud. She looked at Shen Nian'an with eyes full of anticipation. Perhaps, Nian'an truly did possess extraordinary talent in business.

In the afternoon, the exhibition remained bustling with activity. Lin Wanqiu's "Natural Delight" became a dark horse at the exhibition, attracting the attention of many distributors thanks to its superior quality, exquisite packaging, and excellent reputation.

Mr. Wang, a distributor from a neighboring city, praised "Natural Flavor" products after tasting them: "Mr. Lin, your products are outstanding! I'd like to discuss cooperation with you and introduce 'Natural Flavor' to our city for sale. What do you think?"

Lin Wanqiu was overjoyed; this was exactly the result she wanted. She and Shen Tingzhou exchanged a glance, seeing excitement and understanding in each other's eyes. "Manager Wang, it's a pleasure doing business with you!" Lin Wanqiu extended her hand and shook hands with Manager Wang.

Over the next few hours, several more distributors came to Lin Wanqiu's door and signed cooperation agreements. Looking at the thick stack of orders and letters of intent in her hands, Lin Wanqiu felt a great sense of accomplishment. She knew that the market reach of "Natural Flavor" was expanding step by step.

As the sun set, the exhibition gradually drew to a close. The number of people in the exhibition hall slowly decreased, and Lin Wanqiu and Shen Tingzhou began to pack up their booth. Shen Nian'an also helped out, and although she wasn't very strong, she did her job very diligently, helping to hand over items and organize packaging boxes.

"Today has been very fruitful." Lin Wanqiu looked at the orders in her hand, a tired but satisfied smile on her face.

Shen Tingzhou gently hugged her from behind, resting his chin on the top of her head, and said in a tender voice, "You've worked so hard, Wanqiu. You're amazing!"

Lin Wanqiu nestled in his arms, feeling his warm embrace, her heart filled with happiness. "This isn't just my achievement; your help and support have also played a part," she said.

Shen Nian'an ran over and hugged Lin Wanqiu's leg: "Mom, I helped you with chores today too!"

Lin Wanqiu bent down, picked up her son, and kissed him on the cheek: "Yes, our Nian'an is the best! He did a great job today."

Shen Tingzhou looked at his wife and children in his arms, his eyes filled with tenderness. He knew that their lives would only get better and better.

After packing up their booth, the three of them rode their bicycles home. The setting sun cast long shadows, and although the cold wind was still biting, it couldn't dispel the warmth and hope in their hearts.

Lin Wanqiu glanced back at the receding exhibition hall, her heart filled with anticipation. The success of this exhibition was just the beginning. In the future, she would take "Natural Delight" to a wider world, allowing more people to enjoy healthy and delicious food. And Shen Tingzhou, by her side, would always be her support.

At the same time, she also noticed Nian'an's talent in mathematics and his interest in business. Perhaps it was time to gradually let Nian'an get involved in the family business; maybe he could become a capable assistant to her and Shen Tingzhou in the future, carrying forward "Natural Flavors." This idea took root in her heart, filling her with even more anticipation for the future.
