### 这不是重复的 issue

- [x] 我已经搜索了 [现有 issue](https://github.com/DIYgod/RSSHub/issues)，以确保该错误尚未被报告。

Start by reproducing the /newrank/wechat/:wxid route with the provided carrotchou URL and compare its RSS output with the linked expected feed. Read the related WeChat public-account route documentation and trace the route entry point to find why only the account title is returned. Done means the route provides a readable, complete RSS feed rather than title-only information.
