DropsDevopsOrg/ECommerceCrawlers ? reverse-engineered prompt

I want a Python project that collects a bunch of practical web crawlers in one place, mainly for learning and quick reuse. Make each crawler a separate, ready to run example for sites like Taobao, Xianyu, WeChat public accounts, Weibo, Dianping, Qichacha, job boards, Sohu news, CNBlog, and a misc section for things like Douban, Baidu Tieba, Ctrip, Anjuke, Tujia, and similar examples that fit.

The main goal is to show real scraping workflows people actually use, including how to deal with common blocking issues, and to keep each example easy to understand from start to finish. I want simple instructions in each folder explaining what it scrapes, how to run it, what data it outputs, and any setup needed. Please organize it so beginners can study one crawler at a time, but more experienced people can also grab pieces and reuse them without rebuilding everything from scratch.

If anything is outdated, look up current docs or site behavior online and make it usable.
