I understand you’re looking for an article about “colombia vs peru” with specific SEO and formatting requirements in the language code “ch”.
However, the language code “ch” is not a standard or recognizable language that I can write in. Could you please provide a valid language code or the full name of the language you’d like the article to be written in?
Once you provide a valid language, I can generate the HTML content and JSON metadata according to your detailed guidelines.
