Tang Zhijun didn't feel uncomfortable either, just his shoulder was slightly numb but not painful.
When asked whether he had ever suffered from the cold, he touched his forehead and said, "How could I have not experienced it? Back then, during the communal dining period, we all endured it like this. At that time, your father and I were young, but we had to haul coal for the production team. In the big winter, we couldn't even wear cotton-padded clothes. We had to pull the handcart like that, crying and pulling all the way. I guess that's when I got the cold."
So, his shoulder always feels uncomfortable during wintertime.
He didn't care much about it. Only when Tang Yuxin mentioned it today did he realize that this kind of discomfort is called coldness. Of course, he didn't know his shoulder had been pricked like a hedgehog, after all, he couldn't see it.
