In the public art project "Song Dong: Eating the City", the artist meticulously constructed a city out of cookies and candies that emitted a tempting aroma but was destined to be destroyed. Concurrently, we have also planned a "Cookie Architect Workshop" specifically for children, inviting them to emulate the artist and use cookies to design and erect cities, encouraging them to step into the role of "Cookie Architects" and focus on the cities we live in daily life, using cookies and other ingredients to complete small tasks such as urban architectural design and construction. In the process of design, creation and sharing, children can understand the creative motivations and methods of artists, and actively engage in independent thinking and free exploration of topics such as the relationship between "self" and "city", the distance between "daily life" and "art".
