To significantly mark the approaching momentous “Royal Coronation Ceremony” of H.M. King Maha Vajiralongkorn, a very special lecture depicting the ancient, traditional and cultural heritage of the Thai customary royal practices, was organized at Assumption University. Such a very worthwhile lecture was presented by an expert and knowledgeable Dr. Apichart Intravisit, Program Director, Creative Communication Study, AU Graduate School of Business. The enlightening talk featured relevant historical background and educational information of the meticulous ceremony traditionally, ceremonially and elaborately performed up to the very single steps whenever the new Thai king was crowned from the ancient era up to the very present moment when H.M. King Rama X will be officially and ceremonially crowned during this very rare and highly significant royal coronation ceremony scheduled on May 4, 5 and 6, 2019.
