我使用tikzpicture环境生成了下图。我对最左边生成的箭头不满意，箭头从框指向${\bf{Spectral Curve}}$，${\bf{Quantum curve}}$反之亦然。我在下面给出了我的代码。如果可以提出一些修改建议，那将会很有帮助。
\begin{tikzpicture}
[block/.style={rounded corners, minimum width=3cm, minimum height=2cm,draw}]
\label{Qflow}
\node[block] (1) {spectral curve\\ $$ A(x,y)=0$$};
\node[block, right=-.5 and 2 of 1] (3) {correlation differential $\omega_{g,n}$};
\node[block, right=-.5 and 2 of 3] (5) {Free Energy};
\node[block, below=of 5] (6) {Partition Function};
\node[block, left=-.5 and 2 of 6] (4) {Schr\"{o}dinger equation};
\node[block, left=-.5 and 2 of 4] (2) {Quantum curve};
\begin{scope}[->, shorten >=1mm, shorten <=1mm]
\draw (1) to[out=0,in=180] (3);
\draw (3) to[out=0,in=180] (5);
\draw (5) -- (6);
\draw (2) -- (1);
\draw (1) to[out=180,in=180] (2);
\draw (4) to[out=180,in=0] (2);
\draw (6) to[out=180,in=0] (4);
\end{scope}
\end{tikzpicture}
