One caller is Nguyen Huu Ho, inheritor of Vietnam's national intangible cultural heritage, Dong Ho folk paintings. The other is Lu Dequan, inheritor of Longtang braised pork, a Liuzhou intangible cultural heritage with over a 100-year history. They met at a Sino-Vietnamese cultural exchange and became good friends through their heritage skills. A bowl of braised pork and a painting carry the warm story of deepened Sino-Vietnamese exchanges and cooperation.
