Can wordpress make the tag implementation have subtags like catalogs with subdirectories?

I am not a programmer. I want to make a website. I need to make wordpress tags have the function of sub-tags. Can it be realized? Can not find anyone to ask, the Internet can not be searched, if it can be achieved, I will find someone to develop, avoid detours, be deceived, ask for advice from kind-hearted people, thank you!

WordPress, tags and categories are actually the same thing, except that they are presented in a different form at the front end. Labels and categories are interchangeable. The official also has a special plug-in. If you want to call down the child tags of this tag on a tag page, it is technically possible, but it is not a native function of WordPress and needs to be developed separately.
