Walking through the North Zone of Dongguan Middle School, visitors encounter a physical record of China’s modern educational evolution. Founded in 1902, the old campus preserves structures from both the Qing Dynasty and the Republic of China. The oldest layer of this history belongs to the Dongzheng Baogong Ancestral Hall. Originally constructed during the Tongzhi reign, it honored four local figures who successfully reclaimed extensive sand fields for the community. Japanese forces destroyed the hall during the Anti-Japanese War, and the community rebuilt it on its original foundation in 1946. This same northern zone also served as the birthplace of the Dongguan Special Branch of the Communist Party in 1923.

A few years later, the campus expanded under the direction of Principal Yuan Changshan. In 1926, with funding from the local Minglun Tang charitable organization, construction began on the site of the former Bao'an Warehouse. Completed in 1929, these three teaching buildings feature reinforced concrete and a south-facing, two-story external-corridor design. Their distinctive roofs earned them the enduring name of the "Green Tile Building."

Today, these structures occupy a protected space within an active school. The old campus was designated a Guangdong Provincial Cultural Relic in 2019. It functions as a gathering place for alumni, preserving the memory of graduates like patriotic general Jiang Guangnai and architect He Jingtang. The architecture continues to shape the institution's identity. The structural design of the Green Tile Building directly inspired the school's modern "Four Beams and Eight Pillars" academic curriculum. Surrounded by ancient camphor trees and calligraphy steles, the historic buildings offer a quiet space where generations of students have studied, gathered, and shaped the region's history.
