Luonan is the hometown of Chinese character culture, and the word Shengcangjie created the characters here, so Luonan is one of the birthplaces of Chinese civilization. On August 4, 2018, the Fifth Plenary session of the fourth Shangluo Municipal Committee of the Communist Party of China discussed and deliberated the opinions on abolishing the establishment of Huayang District in Luonan County. This work is being submitted to the State Council for approval in accordance with the procedures, which means that Luonan County will withdraw in the future.
