Ng Hung On was born in 1935 in his home in Mau Chin, which was part of Nga Tsin Wai. The residential address shown in his birth certificate was No. 10 Nga Tsin Wai. The houses in Mau Chin were larger and more comfortable than those inside Nga Tsin Wai. Outside Nga Tsin Wai, the air was fresher and there was also large open space for drying the grains under the sun. The houses outside Nga Tsin Wai had a pigsty where the villagers reared pigs, cows and poultry such as chickens. In the earlier days, people even had a cowshed outside the house. The houses inside Nga Tsin Wai were small and had no toilets. There were only a room for sleeping and a wok for cooking. Ng Kwong Yip Tso (the father of Ng Hung On’s great grandfather) was wealthy. He owned 5 houses in Mau Chin, each occupied by one of his 5 families. That is, one for great grandfather, one for grandparents, one for granduncle Kuen Sang and his elder brother, one for granduncle Wing Cheung and one for Ng Hung On’s parents. These 5 houses were enclosed by a wall. A large entrance was opened in front of Nga Tsin Wai, inside was a large yard for sun-drying grains, and chickens might walk about in the yard too. Granduncle Kuen Sang owned a 3-storey building at No. 59 Tak Ku Ling Road. He lived in the building on Tak Ku Ling Road, and his elder brother lived in the house in Mau Chin with his family.
