Ng was born in Hong Kong to a family with ancestry from
Panyu,
Guangzhou, Guangdong, China. He is the uncle of footballer,
Ng Wai Chiu. Ng revealed in a stand-up comedy, saying that when he was a child he told his mother that his dream was to get a job that does not need any academic qualification, without a fixed working hours and high pay. Then, his mother asked him to become a beggar. So, he went to
Wong Tai Sin, a famous temple in Hong Kong, to observe those beggars there. He realised that becoming beggar is too busy and need to perform manual labour, which does not suit his free and unconstrained attitude. Consequently, he gave up and decided to become a movie star because being a movie star fulfilled all the condition he requested. During that time, the only way to become a movie star was to get into TVB Training Classes, so Ng signed up. After failing thrice entering the training classes, he eventually gave up. He went for a short period
