Late November.
In the Central Region, temperatures plummeted to about 4 degrees, prompting people to don their winter attire.
In the outskirts of Yuzhou City, at an industrial park, a car glided smoothly along the curves and stopped in front of a three-story factory building.
Two people got out of the car, a tall woman, draped in a black woolen coat, paired with blue jeans and black boots, clutching a brown bag under her arm.
The biting cold wind lifted the hem of her coat, prompting her to tighten it around herself.
The other person wore only a thin long-sleeved shirt and stood in the cold wind.
Shao Shuangshuang took a key out of her bag and unlocked the heavy padlock of the factory.
Jiang Ning stepped forward and gently pushed open the doors, revealing a spacious interior of several hundred square meters.
