我该如何解决 Tikz 结和装饰的问题？

Question

所以我有一个自相交循环，我希望交点看起来像- -。我已经使用了 knot 包，但它似乎不能像我希望的那样适用于我的图表，尽管它可以适用于更简单的图表：

---

    \begin{tikzpicture}
\begin{knot}[
  consider self intersections]
\strand (0,0) .. controls +(3,1) and +(-3,1) .. (1,0);
\end{knot}
\end{tikzpicture}

以下是我的结图的代码：

  \documentclass[a4paper,11pt]{report}


    \usepackage{tikz}
    \usetikzlibrary{calc,fadings,decorations.pathreplacing}
    \usetikzlibrary{decorations.pathreplacing,decorations.markings}
    \usetikzlibrary{fit,calc,positioning,decorations.pathreplacing,matrix}
    \usetikzlibrary{arrows}
    \usetikzlibrary{knots}
    \usetikzlibrary{intersections}

    \begin{document}
    \tikzset{->-/.style={decoration={
      markings,
      mark=at position #1 with {\arrow{>}}},postaction={decorate}}}


    \begin{tikzpicture}


    \draw[ultra thick] (5,3) circle (0.9);
    \draw [fill] (5,0) circle (0.1);

    \begin{knot}[consider self intersections]
    \strand[rounded corners,->-=.163,->-=.435,->-=.795,thick](5,0)..controls +(50:7) and +(130:6)..(5,1)..controls +(50:7) and +(130:7.5)..(5,0.5)..controls +(50:9) and +(130:9.5)..(5,0);
    \end{knot}

\end{tikzpicture}
\end{document}
