798 Art Center (706 Factory) Introduction: is currently the largest zigzag-shaped factory building in the park. The high-space, large-column-spacing architectural structure completely retains the German Bauhaus art style from the beginning of its construction. Paying attention to practicality and simplicity, the space retains the increasingly mottled huge vermilion slogans and abandoned facilities and instruments, making history and art condense here into a huge visual impact, creating a unique atmosphere for art and cultural activities.
