参考文献样式为啥不使用更简单的方式而是自己定义呢？

学校的参考文献样式应该和GB/T 7714-2015差不多，不是可以直接引入`biblatex`解决吗？如下方所示。为什么要自己去定义呢？

```tex
%在导言区加载宏包和文献文件，注意gb7714而不是gbt7714
\usepackage[backend=biber,style=gb7714,sorting=none,doi=false,abbreviate=true]{biblatex}
\addbibresource{yourbibfile.bib}


%在正文打印参考文献清单
\printbibliography[heading=bibliography,title=参考文献]
```

The issue asks why the template defines its own bibliography style instead of using biblatex with gb7714. Look at the .cls file and any .bst or .bbx files to understand the current implementation. Compare with the biblatex approach to see if it meets the university's 2021 requirements. Check if there are existing tests or documentation about bibliography formatting.
