Second, many place names come from ground cultural relics. Such as Thousand Buddha Rock, Pagoda, Golden Pagoda, Bajiao Temple, Datong, White Elephant, Stone Pagoda, Nanyin Temple, Chuanzhu Temple and Feiyun Temple, some place names are related to ancient military activities, such as Meiziguan, Yangliuguan, Shapingguan, Fengmengguan, Yongping Village, Luohan Village, Tianbao Village and Guanyin Village.
Third, there are many place names formed by ancient legends. Such as Taiping, Zen Rock, Stone Footprint, Shuanba, Yuhuanggou, Wulaoyan, Laoguanpo, Baicao, Yushantai, Heshan, Heyouping, Yankou, Fuluba, Qiao Nv, Yuan Yin Bay, Loutan, Chaqi Mountain and Laojuntan. Among them, Taiping is the place of Taiping Town today. According to Dianjiang County Records, it was named after a prince named Yao Huang held a Taiping banquet here. Zen Rock is the place where Mazu, a monk, practiced when he founded Datong Temple in the early years of Zhenguan in Tang Dynasty. Because of his sincere visit, the pale rock wall shines with colorful light. The stone footprints were left by Laozi when he passed by, and Cao Xuequan recorded them in "Notes on Places of Interest in Central Sichuan" in the Ming Dynasty.
Fourth, some place names have obvious geographical landscape characteristics. Dianjiang county is characterized by continuous mountains in the east and west, rolling hills in the middle and streams and rivers around it, with unique geographical landscape. Such as Shuangrufeng, Shiren Mountain, Zhongzuizhai, Hushan, Fenghuangzui, Lion Rock, Maobiliangliang Ridge, Shiling, Sanhekou, Shuanghekou, Tanzikou, Biqiao, Shiping, Duiwodang, Donkey Pond, Jianshan, Gaoshikan, Niutouzhai, Eagle Rock, Shiniutan, Shidanpo, Chessboard, etc.
Fifth, most places in China have the characteristics of immigrant culture. Dianjiang County experienced two major wars in the late Yuan Dynasty, the late Ming Dynasty and the early Qing Dynasty. The sharp drop in population and poor land led to two large-scale "Huguang filling Sichuan" immigration activities in the early Ming and early Qing Dynasties. Immigrants "stick to the standard for a living" and live in groups, so most of them use the surnames of big families, noble families or heads of households to crown place names. Such as Yanjiachang, Baojiachang, Peixingchang, Caojiachang, Dongjiachang, Jiangjiadian, Xiongjiagou, Chengfugou, Ganjiawan and Libaiba, accounting for about 20% of the total number of market towns and natural villages.
