In blockquotes, I can put angle brackets <> with \ before it to not recognize it as HTML tag.
> \<test>
<test>
And in code block, It will not take <> as HTML tag.
```py
>>> repr(min)
'<built-in function min>'
```
(Here I use < and > to represent <> within <pre> <\pre>)
>>> repr(min)
'<built-in function min>'
However, when I put code block in blockquotes, the <> in code block is recognized as HTML tags again and can’t be escaped with \:
>>> repr(min)
'<built-in function min>'
>>> repr(min)
'\<built-in function min\>'
I am not sure if it’s clear enough, I am not familiar to HTML and Markdown
