In Laishu village, Heshan, Jiangmen, a team from South China University of Technology digitized more than 300 pages of the Zhong clan's genealogy page by page and built a genealogy website: authorized descendants can add new generations online, and overseas kin can trace their ancestral origins remotely. From diaolou AR tours to oral-history videos, a thousand-year village's memory is being reborn in the cloud.
