As for Fang Chaoyang, he was studying management.
You could say he was applying what he learned in real time.
Fang Chaoyang was initially managing the factory, where he could apply what his teachers taught him at work.

Zhao Tianhe was skilled with his hands.
But the theory was really difficult for him.
"Sister-in-law, I..."
Yun Xiaoxiao asked Zhao Tianhe to bring his book to her so she could explain it to him.
You couldn't blame Zhao Tianhe; he knew some theoretical knowledge, but just didn't understand it.
Yun Xiaoxiao summarized it simply; there really was no need to memorize everything by rote.
"Sister-in-law, now that you've explained it, I instantly understand what it means."
"My mom is the best."
"Yes, mom is the best."
