How many floors does Hefei No.9 Middle School canteen have?

Fourth floor. According to official website's inquiry, Hefei No.9 Middle School, as of July 25th, 2023, was the root of Hefei education. Its predecessor was initiated by Zhang Chunxiau, the magistrate in the forty-fourth year of Emperor Kangxi of Qing Dynasty (1705), originally named as Hengqu Academy, and later changed to Luzhou Academy. In the 28th year of Guangxu (1902), Li Hongzhang's son and nephew and assistant minister of the postal department changed it to "Luzhou Middle School". These four words "make a heart for heaven and earth, make a life for the people, link the past with the future, and make the world peaceful" inspire students and future generations. The Nine Lieutenant Colonel History Museums will also be built here, so that the century-old famous schools will once again show a new look.
