## When to prefer this

Use this endpoint when you specifically need news results from Baidu — particularly for Chinese-language news coverage, content from Baijiahao publishers, or when researching topics as seen through China's dominant search engine. Prefer this over Google News endpoints when the target audience or content focus is Chinese-speaking markets or mainland Chinese media.

- Invalid language code (ct) returns error or defaults
