At the age of 10, when Elizabeth Grubb joined Central British School, she would stare down at the wooden parquet flooring in the assembly hall and see the black smudged marks where the mosquito coils had burned.
The school had been turned into a Japanese hospital during the second world war and the coils burned next to the beds of the injured and sick.
When she joined the school in 1947, a year before the name of the school was changed to King George V School or KGV, there were no books or supplies, and the teachers had to devise a curriculum and syllabus out of what they could remember from before the war.
Even now, she remembers the teachers' dedication to pupils and their ability to devise lessons that were of interest and required a huge amount of extra work without any materials available.
Mrs Grubb returned to Hong Kong this week for a few days for the first time in 53 years, after leaving KGV at the age of 17 to study at Edinburgh University. She relished the opportunity to return to her old school.
With her husband, George, they are the Lord and Lady Provost of Edinburgh. All four principal cities in Scotland have a Lord Provost, a figurative and ceremonial head of the city. The couple were on a trip to Japan to promote Scottish business and decided to return via Hong Kong.
