他的专业在大学的专业是医生。

I heard the story of the director of Nezha online. His major in the university was medicine. He loves animation, so he chose to spend more than three years studying animation. I heard that when he was making Nezha, he used his medical knowledge in the animation, which shows that no knowledge is lost. I also heard that many Chinese animation companies worked together to make movie, which shows that unity is strength.

因为他喜欢动画，他选择用了三年多来学动画片制作。

我听说他在做《哪吒》时，他用到了他的医生知识，说明学有所用。

我也听说很多中国动画公司一起做了这场电影，说明团结就是力量。

我在网上听说了《哪吒》导演的故事。

他大学时的专业在大学是医生学。

“医生”是职业，“医学”是医疗领域的学科
