The booklet is printed on A5 pages which can be photocopied in A4 format for creating PDF files, which is in traditional Chinese script and bound in the conventional fashion, and is ideally read after rotating clockwise in the viewer. It was compiled by the late Headmaster Mo Man Pan. Mo (巫; in Cantonese pronunciation, and pronounced as “Wu” in Mandarin/Putonghua). The Mo genealogical information has been extensively updated since the last issue of the Publication of the Hong Kong Mo clansmen’s Association. Data are very much based on the branch of the Mo clan, who moved south to Tan Ka Wan (蛋家灣), N.T. (新界), Hong Kong in the Qing Dynasty, then to Yuen Long (元朗) as well as other parts of the New Territories, and overseas. The family tree contains detailed description of the families belonging to descendants of the brothers originally migrated to Ta Ka Wan, up to Spring 1999 through various generations (25 in total based on the Ninghua, Fujian/Luogang, Guangdong, lineage that has historical records available), including that of the uploader Mo Chi Leung (巫志良).
