This is the second of two photos I recently received from a family friend. I interpret the title at the top as photo taken in 1936, the school's name - likely located in Kowloon. It mentions " 中學" but considering the age of the students, it appears they just started an early level/grade at this high school. I have no knowledge how the schools' structure worked in those days.
What is certain is that my mother was in this photo - 5th row (note there are 7 rows), first on left. The girls' school uniform matched those of her friends in another photo likely taken in 1937, on the occasion of the get-together of friends some continued to attend this school while a few joined Maryknoll Convent School.
