I think the usefulness of textual research depends on the situation. First of all, I am a college student in Shandong. Before my sophomore year, I was also a research enthusiast, trying my best to get all kinds of certificates, and now I realize some problems.

First of all, it depends on what kind of certificate it is, and whether it is a "universal" certificate that can be tested by all kinds of majors, such as CET-4 graduation, Putonghua certificate examination, teaching resources and computer certificate, which are very useful in practice.

Then I'll see if my major has a special certificate. For example, my mechanical major will have electrician certificate, fitter certificate, accounting major will have accountant qualification certificate and teacher qualification certificate. At this time, it depends on whether this certificate has anything to do with my future career. Of course, teaching resources are useful, but electrician certificates cost money, so it's a bit of a waste of time to take this exam.

The third is some social proof, such as psychological proof, proof of one building and two buildings. Most of these certificates will be advertised on various platforms, which are mixed. You can think about why you want to advertise if they are particularly useful. Moreover, many of these certificates are not recognized, and they are used to cut leeks. It is recommended to know them carefully before deciding not to make leeks.
