[1] Ng attended Raimondi College, on the Mid-Levels in the City of Victoria on Hong Kong Island – which served as the polling station of the constituency he later represented.

[3] In June 2018 he was attacked by a resident while promoting the annual 1 July march, apparently over his opposition against local liquor licences.

[4] His majority in the constituency was further increased in the 2019 elections, to 57.28% (2,672 votes) with a gain of 6.38%, amidst the large wave of anti-government protests.

He was selected to run for the seat of Maiden Erlegh and Whitegates in the Wokingham Borough Council in the 2024 local elections.

[8] Ng is the second from Hong Kong to sit on an English local authority[9] after Ying Perrett who secured a seat at the Bisley & West End ward of Surrey Heath Borough Council in the November 2023 elections,[10] and the first who had held an elected office in Hong Kong.
