What newspapers and periodicals can publish middle school students' calligraphy works?

I will give you several websites, such as China Calligraphers Forum, Calligraphy Commune, China Calligraphy Home Network, China calligraphy net Forum, etc. There are detailed exhibition columns on it, including those of primary and secondary schools.

There are also periodicals that publish professional articles. If it is better to publish below the provincial level, some periodicals still have to charge a part of the page fee. I recommend several periodicals that are basically free of charge but still pay remuneration, such as Youth Calligraphy, Calligraphy Newspaper, Calligraphy Guide and Art Education Research.
