LettersTo friends who loved her, Leung Chai-yan was kind, brilliant and brave
Readers pay tribute to the late daughter of former chief executive Leung Chun-ying, and discuss ways to promote pet-friendly transit, making air quality information more accessible, and Chinese soldiers involved in the Ukraine war

Chai-yan was both intelligent and studious, with the potential to pursue whatever career she wanted. She was multitalented: a phenomenal mathematician and linguist; a gifted harpist and pianist from a young age; and someone who could bring down the house in a comedic school play. Her sense of humour was singular and sometimes misunderstood. It lives on in the photos, videos and voice notes still shared between us, each one a reminder of how sharply funny and creative she could be. We’ll treasure them always.
To us, Chai-yan always emphasised her deep respect and love for her family and her pride in their many accomplishments. She was a devoted and admiring sister. She was excited to give us updates on the impressive international work of her sister Chung-yan, with whom we were also at school.
