在评论和其他一些资源的帮助下，我设法画出了我想要的东西，但我敢打赌它并不完美。我把它放在这里，供可能有同样问题的人参考，希望它能有所帮助。

\documentclass{article}
\usepackage{tikz}
\usepackage{amsmath}
\usetikzlibrary{shapes,arrows}
\usetikzlibrary{calc}
\usetikzlibrary{fit,positioning}

\begin{document}

\tikzstyle{block} = [rectangle, draw,
    text width=5em, text centered, rounded corners, minimum height=2em]
\tikzstyle{entity} = [rectangle, draw, text centered]
\tikzstyle{line} = [draw, rounded corners, -latex']

\centering
\begin{tikzpicture}[node distance = 4em, auto]

  \path [line] (up_phi) -- (inc_i);

  \node [block, below of=inc_i, node distance = 5em] (f) {\footnotesize $f \in \Phi_{l_i}$};
