那是几年前的情况了。现在，好多大学都采用学分制，也开设了好多选修科目，鼓励学生多接触不同的知识。而且，换专业也比过去容易多了。总之，现在中国大学的制度和氛围早就不像以前那么死板了。

That's how things used to be in the past. Now, a lot of universities are credit-based, and they've started up a lot of elective courses. They encourage students to try out unfamiliar fields of knowledge. And changing your major is much easier today than it used to be. In sum, for a long time now modern Chinese universities' rules and atmosphere haven't been that rigid.
