  若此处输入的是栏目 ID（而非南方号 ID），则该接口会返回与输入栏目相关联栏目的文章。例如，输入栏目 ID \`38\`（广州），则返回的结果还会包含 ID 为 \`3547\`（市长报道集）的文章。

  1.  \`pc.nfapp.southcn.com\` 下的文章页面，可通过 url 查看，例：\`http://pc.nfapp.southcn.com/13707/7491109.html\` 的栏目 ID 为 \`13707\`。
  2.  \`static.nfapp.southcn.com\` 下的文章页面，可查看网页源代码，搜索 \`columnid\`。
  3.  [https://m.nfapp.southcn.com/column/all](https://m.nfapp.southcn.com/column/all) 列出了部分栏目，\`id\` 即为栏目 ID。`,

    1) 南方号 uses responseColumn.linkUrl, e.g. https://static.nfapp.southcn.com/nfh/shareNFNum/index.html?nfhId=3392;
    2) 栏目/频道's responseColumn.linkUrl is empty, we use its subpage on 南方+ mobile site, e.g. https://m.nfapp.southcn.com/38;
    3) But https://m.nfapp.southcn.com/${columnId} may still be invalid for some higher-level columns, e.g. 20.
