The Pui Ching Middle School has a rich history closely tied to Hong Kong and Macau and even an influx of students following anti-Chinese deportations from Indonesia in 1950. The confusing (for a casual reader) and tumultuous history of Pui Ching and the No. 7 Middle School are documented in these separate Wikipedia entries for Pui Ching and the No. 7 Middle School.
Pui Ching's school motto originally quoted Deuteronomy and Psalms and is now seen as reflecting a combination of Western and Confucian values. The No. 7 Middle School's more secular motto: "Love, honesty, truth, perseverance."
Pui Ching school clearly looks forward rather than back, with a series of prominent friezes and posters facing the school entrance focusing on science and technology. This plaza, though, takes some time to reflect on its history. It's a pleasant, shaded public space lined with plaques including one devoted to Miss Emma Young, a Baptist who came to Guangzhou and started a school for girls which in its first year in 1888 had only six students but is seen as the genesis of the No. 7 Middle School.
