Ng Hung On is a member of Ng Hon Ko Tso branch. Ng Hon Ko Tso’s posterity includes the following households: Ng Kwong Yip’s family, Ng Chin Hung’s family, Ng Siu Hung’s family and Ng Fat Chuen’s family. At present, Ng Hon Ko Tso has 4 managers, namely Ng Fat Chuen, Ng Hung On, Ng Cheung Wah and Ng Chin Hung. A manager is not decided by election, the post is generally passed on from the father to the son or filled through the clan senior’s appointment of someone who has the time for it. There is no fixed number of managers. In the past, there were 5 managers, so when the property in Choi Hung Road was purchased, 5 copies of title deed were prepared. The managers do not have regular meetings. They only meet when there are issues for discussion. The ancestral trust had always been managed by Ng Hung On’s father and Ng Fat Chuen. Ng Hung On became the manager more than 20 years ago and represented the Kwong Yip Tso branch. His father had advised him against the appointment out of worry that he might not be able to make time from his occupation as a minus driver for it. But, Ng Hung On did not mind because it would be a service to the clan. Besides, it would not occupy too much of his time. So, under Ng Fat Chuen’s encouragement, he eventually took up the post.
