These inscriptions embedded in the walls are cultural relics collected and protected by the cultural relics department of Wudang Mountain from the stone tablets of the Grinding Needle Well. Most of the merit tablets donated by people from various places for the repair of the grinding needle well are important materials for studying the religious beliefs of different regions and social strata. They are also historical materials for researching the history of Wudang Mountain and the social production, life, culture and economic conditions at that time.
