  > 上面的榜单 / 集合并没有列举完整。
  >
  > 如何找到榜单对应的路由参数：
  > 在豆瓣手机 APP 中，对应地榜单页面右上角，点击分享链接。链接路径 \`subject_collection\` 后的路径就是路由参数 \`type\`。
  > 如：小说热门榜的分享链接为：\`https://m.douban.com/subject_collection/ECDIHUN4A\`，其对应本 RSS 路由的 \`type\` 为 \`ECDIHUN4A\`，对应的订阅链接路由：[\`/douban/list/ECDIHUN4A\`](https://rsshub.app/douban/list/ECDIHUN4A)`,
