Time may have eased the pain, but Ms Leung still weeps when she recalls the letter Chan wrote from Stanley Prison telling her he would never return.
It read: 'I will probably be killed. There is nothing you can do except trust in God. Please bring up our children and do not give them away.' Ms Leung recited the lines repeatedly after laying flowers on her husband's grave at Stanley Military Cemetery.
Dabbing her eyes, she said: 'My husband loved me very much. He was very kind and protective. He tried to make me as happy as possible.
'He was a brave, active person and very proud of Hong Kong. He wanted to be a policeman after the war.' Following the Japanese invasion, Chan left for Shaoguan, Guangdong, telling his wife that he was going in search of a job.
But when he returned she discovered he was working as a spy for the British Army Aid Group. The organisation operated in Japanese-held territories, helping prisoners of war and gathering military intelligence.
Ms Leung told how the young family snatched precious moments together on his rare stopovers in Hong Kong. But Chan always had to be gone by dawn.
