This is the complied result of my code:enter image description here And this is my code:

\documentclass{article}
\usepackage{tikz}
\usepackage{ctex}

\begin{document}
\usetikzlibrary{shapes.geometric,arrows,positioning}
\flushleft
\begin{tikzpicture}[level1/.style={regular polygon, regular polygon sides=3,fill=orange,draw=black, minimum width=3cm, minimum height=2cm},level2/.style={rectangle, rounded corners, fill=purple, minimum width=3cm, minimum height=2cm},level3/.style={trapezium,trapezium angle=70,fill=blue,draw=black,minimum height=1.3cm}]
\tikzset{trapezium stretches=true}
\node(a1)[level1]{雅思一对一精品教程(推荐)};
\node(b1)[level2,below=1cm of a1,xshift=-5cm]{雅思口语提升班};
\node(b2)[level2,right=of b1]{雅思听力提升班};
\node(b3)[level2,right=of b2]{雅思阅读提升班};
\node(b4)[level2, right=of b3]{雅思写作提升班};
\node(c1)[level3,below=of b1]{夯实基础：雅思语法讲解};
\node(c2)[level3,right =  of c1]{夯实基础:雅思发音讲解};
\node(c3)[level3,right= of c2]{夯实基础: 雅思词汇讲解};
\end{tikzpicture}
\end{document}

As you can see, the picture is ugly and nonsymetrical. I am looking for some way to make it more symetrical. I guess I could math it out and calculate the xshift I need, but this is not what I am looking for. Is there an easier way that let tikz automatically align nodes?

Let me first apologize for not being able to use your characters. However, the answer to the question is: yes, e.g. with a matrix of nodes. BTW, you can set the node distance, then you do no longer have to say below=1cm.

\documentclass[tikz,border=3mm]{standalone}
% please put the libraries in the preamble
\usetikzlibrary{shapes.geometric,positioning,matrix}
\begin{document}
\begin{tikzpicture}[level1/.style={regular polygon, regular polygon sides=3,
fill=orange,draw=black, minimum width=3cm, minimum height=2cm},
level2/.style={rectangle, rounded corners, fill=purple, minimum width=3cm, 
minimum height=2cm},level3/.style={trapezium,trapezium angle=70,fill=blue,
draw=black,minimum height=1.3cm},node distance=1cm]
\tikzset{trapezium stretches=true}
\node(a1)[level1]{AAAAAAAAA(AA)};
\node[matrix of nodes,below=of a1,inner sep=0pt,nodes={level2,anchor=center},column sep=1cm] (b)
 {AAAAAAA & AAAAAAA & AAAAAAA & AAAAAAA \\};
\node[matrix of nodes,below=of b,inner sep=0pt,nodes={level3,anchor=center},column sep=1cm] (c)
{AAAA:AAAAAA & AAAA: AAAAAA & AAAA: AAAAAA\\};
\end{tikzpicture}
\end{document}
