我的最终节点存在尺寸/对齐问题。
确实，我笨拙地打印了节点，然后使用 fit node 来覆盖多个子节点。
它并不漂亮。一定有更聪明、更自然的东西。

答案1
从现有节点到现有节点的北边缘（不是北边缘的中心）绘制垂直线的语法是
\draw (node1) -- (node1.south|-node2.north)
因此，消除矩阵的最后一行，并将“投资者”节点放置在您想要的位置。我将它们放在1.2cm矩阵的最后一行下方。第一个在节点下方；第二个在和m-4-2的中点下方。m-4-4m-4-5
然后命令
\draw[myline] (m-4-1.south) -- (m-4-1.south|-new1.north);
将从(m-4-1.south)垂直向下绘制到 的北边缘(new1)，这就是我命名的第一个“投资者”节点。
