Ma Sui Wai’s father came to Hong Kong from the Mainland illegally. His mother also came to Hong Kong in 1945. Ma Sui Wai was born in their Sung Wong Toi home in 1946. After he was born, his father tried to look for a new home. He could not afford to rent a flat in Nga Tsin Wai, so he built a wooden hut on Pei Pin Street, which was adjacent to Nga Tsin Wai, with the consent of the Nga Tsin Wai village headman. At the time, on the right of Nga Tsin Wai was Nam Pin Street. Some brick houses were built on Nam Pin Street, but most houses were wooden huts. Ma Sui Wai remembered that a dozen houses were built on Pei Pin Street when he was 8 to 10 years old. His neighbours were mainly Haifeng natives who moved there from Sung Wong Toi along with them. Both his parents were Haifeng natives, they spoke Haifeng dialect. Ma Sui Wai talked with people outside the family in Cantonese, and talked with his mother in the Haifeng dialect. Usually, his mother only spoke Haifeng dialect because she was shy and felt uncomfortable talking in Cantonese. Besides, all her neighbours were Haifeng natives.
