quote在 markdown 中重新定义创建具有背景颜色和边框的漂亮块引用之后，我该如何返回到之前的quote定义，
这是未知的，因为 markdown 首先初始化了它，而我不知道如何、用什么？
这里是pdf显示我遇到的问题：我决定在块引用上放置一个带边框的绿色背景，然后当我决定这样做时，我无法完全删除这个背景和边框……
我没有办法确保回到以前的状态。
这pdf紧接着是生成它的 markdown 文件。

Defining `quote` to nothing with a `\renewtcolorbox{quote}{}` doesn't return to normal:

How may I rollback `quote` to its previous definition?
considering that I don't really know what it was, only markdown knows how it initialized `quote` (it might even depend even on your operating system, distro, environment flavor...)
so that they will look as if I'd never changed them...
\cadreAttention

I believe that I don't really need to know what this initial definition is.
I think (but you might have a better idea) that what I need is to be able to save it once, and to restore it each time its needed.
So that I will have command in my markdown like:
/saveQuote
abc
/cadreAvantage
> def
/restoreQuote
jkl
/cadreAttention
> mno
/restoreQuote
> this one is the normal blockquote

您可以quote通过以下方式保护环境：
\let\oldQuote\quote
\let\endoldQuote\endquote
并使用以下命令恢复：
\let\quote\oldQuote
\let\endquote\endoldQuote
