Abandoned primary schools are revitalized with “earthy snacks” to keep the “nostalgia on the tip of the tongue” The Lao Dao Baijiang Intangible Cultural Heritage Workshop based in this place was busy working non-stop. Many of these pastries still retain the "earthy" packaging style.

In 2021, it invested more than 5 million yuan to carry out protective restoration of an abandoned primary school that was more than 50 years old, and summoned rural craftsmen to jointly build this workshop.
