Ng Hung On was born in 1935 in Mau Chin, Nga Tsin Wai. He is a descendent of the 26th generation of the Ng’s Clan in Nga Tsin Wai and belongs to the branch of Ng Hon Ko Tso. His family was prestigious in the era of his great-grandfather when the branches lived in large houses enclosed by walls and owned a large number of farmlands and houses. Ng Hugn On’s father was a sailor before the Second World War, his mother came from a peasant family in Tseung Kwan O. When the Japanese armies occupied Hong Kong, they demolished all the houses in Mau Chin for extension of Kai Tak Airport. As a result, the Ng Clan lost all its assets. Ng Hung On led an unstable life. When he was 9 years old, he was sold as a child labour to a remote relative who lived in Sha Kok Mei, Sai Kung. After the War, he was redeemed and lived with his parents in their home on Tak Ku Ling Road. Ng Hung On had received several years of free education and started to work at 19 as a neon sign technician. In the early 1970s, he became a minibus driver, an occupation which he had worked until he retired at the age of 68. Ng Hung On got married in 1969 and moved into a public housing flat in Tsuen Wan shortly after. Ng Hung On has a strong sense of belonging to Nga Tsin Wai. He is enthusiastic in the affairs of the Ng Clan and serves as the manager of Ng Kwong Yip Tso, Ng Hon Ko Tso and Sam Sing Tso.
