Ng Hon Ko Tso ratified Ng Hon Ko of the 19th generation as its branch’s Tai Gong and is now in its 27th or 28th generation. The existing members of Ng Hon Ko Tso consisted of 24 families descended from the two lines of Ng Kan Yam and Ng Chiu Yam. Before the 1941 to 1945 war, most clansmen lived in the big house at Mau Tsuen outside Nga Tsin Wai. A few also resided inside the village or on Lamma Island. This branch’s ancestral grave is located in Kwun Yam Shan and worship is held during every ninth lunar month. Ng Hon Ko Tso has its own branch ancestral trust and owned agricultural lands in Tai Hom Tsuen as its main properties. Compensation for these holdings was deposited into bank accounts when the lands were expropriated by the Government. This branch’s members are also involved in the management of Ng Yat Un Tso’s properties and have management representation in Ng Wai Wing Tso and Ng Yat Un Tso Limited.
