The name is said to signify "Cultivate the children of the Church so they can be spared from the adulteration of secularism and build characters of uprightness and integrity".

[citation needed] For the first 30 years after its inauguration, the school experienced financial difficulties and suffered several temporary shutdowns.

In 1907, Pui Ching purchased land in the Dongshan district of Guangzhou with the long-term goal of opening a school site there.

[citation needed] In 1918, Pui Ching alumnus Huang Qiming was appointed president and launched a fundraising campaign to mark the school's 30th anniversary.

Pui Ching students created a campaign called "The Anti-Japanese National Salvation", and organized propaganda teams to encourage patriotism.

In January 1938, the school moved from Guangzhou to Macau, and subsequently to Heshan, Ping Shek, Guilin, Hunan and Jiangxi.

Zhao Bilan, the widow of President Huang Qiming who had died in Hong Kong in 1939, continued to supervise the Macau school.

In 1952, parents of Pui Ching students, Mr. Ho Yin and Mr. Chong Chi Kwong, purchased nearly half of Lou's Garden as the school's permanent site.

In 2003, President Li Xiangli articulated a ten-year development plan for modernizing the campus, with the goal of constructing new classroom buildings.

Pui Ching values both academic performances and moral behavior as a crucial part of student training and school life.

Under these policies the school has autonomy in the selection of textbooks, the decision of what to teach in different educational stages, and the depth and difficulty of the content to be taught.

Pui Ching has a strong reputation for STEAM Education relative to other schools in the Pearl River Delta.

During that period, more than 90% of the school's graduates proceeded to tertiary academic institutions, but the students had to manage large course loads.

[4] Chan Jileung (陳子良) and Wong Chao Son (黃就順), Pui Ching history and geography teachers,[5] told Clayton that there were several reasons for this: the lack of a textbook about Macau history,[6] the fact that such knowledge did not factor into the admissions processes of foreign universities, the already high course loads faced by students, and political sensitivities.
