The four-egg mooncake factory in Hanoi has recently come under scrutiny as discussions about its pricing and product quality have erupted on social media. Despite the noise outside, the factory's atmosphere was surprisingly calm during our visit on July 14, 2026. The facility, located in a narrow alley on An Duong Street, was mostly quiet, with only a few motorcycles parked and a handful of people passing by.

According to an employee, who declined to identify herself as a representative of the factory, production errors are inevitable in any business. She emphasized that the factory takes full responsibility for any defective products and offers complete refunds to customers. "In production, mistakes can happen, but we ensure that we compensate our customers fully for any issues," she stated.

This controversy began when an online seller, who previously collaborated with the factory, publicly criticized the quality of the mooncakes, claiming that there were numerous defects in recent batches. The employee acknowledged that while errors can occur, the factory has always been proactive in addressing these issues. "If there are any defective mooncakes, we take them back and refund our customers. We bear the losses ourselves," she explained.

The factory has been in operation for several decades, and the employee noted that they have received complaints in the past, but they strive to maintain high standards. "We have been in business for many years, and we have always focused on quality. Our products are handmade, and while we use some machinery, the essence of our craftsmanship remains intact," she added.

As for the pricing controversy, the employee remarked that both buyers and sellers have their interests at heart. "It's normal in business for buyers to want lower prices while sellers aim for higher profits. We sell at our base price, and how others price their products is their business," she stated.

Despite the ongoing discussions online, the factory has chosen not to engage further. "We prefer to let our customers and the public form their own opinions. We won't comment on the situation; we believe the market will judge who is right or wrong," she concluded.
