[1] Because of the Civil War in 1949, True Light Girl School in Guangzhou moved to Hong Kong and placed on Waterloo Road No.115 (which is Kowloon True Light Primary School for now) and named it as Kowloon True Light Secondary School.

On 16 June 1872, True Light School, a primary school, was founded in Guangzhou on the Chinese mainland by Harriet Newell Noyes, a missionary from the American Presbyterian Church.

In 1917, the True Light Middle School was established in Guangzhou as a secondary section.

In 1949, due to the communist takeover of Guangzhou, the school transferred to Hong Kong.

It was finally relocated to the current site in 1960, with an affiliated primary school and kindergarten opened on its original campus on Waterloo Road.
