如何在 tikz 中绘制重叠的圆圈，每个圆圈内都有文字

Question

我的目标是使用 Tikz 绘制三个圆形/椭圆形的图片。三个节点应该重叠。在 powepoint 中，很容易制作这样的图形。然而，在 Tikz 中，我在显示重叠方面遇到了一些问题。

像这样？

\documentclass[xcolor=table]{beamer}
\usetheme{CambridgeUS} 
\usepackage{tikz}
\usetikzlibrary{positioning,shapes.geometric}
\usepackage{amsmath}
\begin{document}

\begin{frame}[t]
\frametitle{Frame Title}

  \begin{tikzpicture}[font=\tiny,
    elli/.style={ellipse,text width=5cm,align=center,
        minimum height=4cm,inner xsep=-1em,inner ysep=-1em,draw}]
 \node[elli] (TL) {Short term
 \begin{itemize}
  \item DO 1  DO 1  DO 1  DO 1 DO 1 DO 1 Text
  \item DO 2 Text DO 2 Text  DO 2 Text DO 2 Text
  \item DO 3  Text  DO 2 Text  DO 2 Text
  \item  DO 4 Text  DO 2 Text  DO 2 Text  DO 2 Text 

  \end{itemize}
  };
  \node[elli,right=-0.5cm of TL] (TR) {Short term
  \begin{itemize}
    \item DO 1  DO 1  DO 1  DO 1 DO 1 DO 1 Text
    \item DO 2 Text DO 2 Text  DO 2 Text DO 2 Text
   \end{itemize}

   };
  \path (TL) -- (TR) node[elli,midway,below=0.8cm] (B) {University
    \begin{itemize}
     \item DO 1  DO 1  DO 1  DO 1 DO 1 DO 1 Text
     \item DO 2 Text DO 2 Text  DO 2 Text DO 2 Text
     \item DO 2  DO 2  DO 2  DO 2 DO 2 DO 2 Text
  \end{itemize}};
\end{tikzpicture}
\end{frame}
\end{document}   

或者不进行调整，但使用交叉点。

\documentclass[xcolor=table]{beamer}
\usetheme{CambridgeUS} 
\usepackage{tikz}
\usetikzlibrary{positioning,shapes.geometric,intersections}
\usepackage{amsmath}
\begin{document}

\begin{frame}[t]
\frametitle{Frame Title}

  \begin{tikzpicture}[font=\tiny,
    elli/.style={ellipse,text width=5cm,align=center,
        minimum height=4cm,inner xsep=-1em,inner ysep=-1em,draw}]
 \node[elli,name path=L] (TL) {\textcolor{red}{\underline{\normalsize Short term}}
 \begin{itemize}
  \item DO 1  DO 1  DO 1  DO 1 DO 1 DO 1 Text
  \item DO 2 Text DO 2 Text  DO 2 Text DO 2 Text
  \item DO 3  Text  DO 2 Text  DO 2 Text
  \item  DO 4 Text  DO 2 Text  DO 2 Text  DO 2 Text 

  \end{itemize}
  };
  \node[elli,right=-0.5cm of TL,name path=R] (TR)
  {\textcolor{red}{\underline{\normalsize Short term}}
  \begin{itemize}
    \item DO 1  DO 1  DO 1  DO 1 DO 1 DO 1 Text
    \item DO 2 Text DO 2 Text  DO 2 Text DO 2 Text
   \end{itemize}

   };
  \path[name intersections={of=L and R}] (intersection-2) 
  node[elli,anchor=north] (B) {\textcolor{red}{\underline{\normalsize
  University}}
    \begin{itemize}
     \item DO 1  DO 1  DO 1  DO 1 DO 1 DO 1 Text
     \item DO 2 Text DO 2 Text  DO 2 Text DO 2 Text
     \item DO 2  DO 2  DO 2  DO 2 DO 2 DO 2 Text
  \end{itemize}};
\end{tikzpicture}
\end{frame}
