爬取知乎过往两年的热搜问题和回答。
multiple code conjunction, shit codes, sorry.
本质是多个仓库的结合体，垃圾代码，请见谅。
Requirements:
pip install beautifulsoup4
pip install lxml
需要安装beautifulsoup4库和lxml。
Usage:
Download .md from https://github.com/justjavac/zhihu-trending-hot-questions
put uv.py into all .md files directory.
python uv.py
default only download the first question, remove the break to download all.
用法是先下载存有问题链接的所有md文件，然后把uv.py放到同一目录下，再运行即可，默认只下载第一个问题的五条回答，可通过break语句控制。
