在思维导图中画箭头

我使用 PGF 手册来帮助我绘制如下图所示的图形。 使用 PGF 绘制的思维导图

但我想添加一些箭头来指示事件的流程，就像这张图片一样（我用 Paint 制作的）

使用 Paint 绘制的思维导图

我不知道该怎么做，因为这不是一个简单的箭头。这是我的代码：

一个想法：由于更改单个连接栏并不容易，您可以在背景中绘制箭头（我使用了库backgrounds和Stealth来自库的自定义箭头提示arrows.meta）：

附注：请注意加载的某些软件包：subfigure和epsfig已过时，不应再使用；它们已被前者subfig或取代，后者取代。此外，您要加载两次和；加载一次就足够了。更危险的是：您要加载两次：一次带有选项，然后不带选项；这可能会产生冲突。在现代系统上，无需明确指定驱动程序，因此，而不是subcaptiongraphicxgraphicxgraphicsgraphicxamsmathcentertagshyperref
