我给一个最小工作示例
```
\documentclass{article}
\usepackage{amsmath}
\usepackage{hyperref}
\begin{document}
\begin{equation*}
a\tag{$ \heartsuit $}\label{eq:gougu3}
\end{equation*}
\clearpage
\begin{equation}
b\label{eq:gougu4}
\end{equation}
\clearpage
This is a cross-reference for formula \eqref{eq:gougu3}.
This is a cross-reference for formula \eqref{eq:gougu4}.
\end{document}
```
