Lingguang Pagoda, located on the top of Tashan Mountain in the northwest suburb of Changbai Town, Changbai Korean Autonomous County, Jilin Province, is 820 meters above sea level and has a history of more than 1,000 years. Lingguang Pagoda is the only ancient architectural relic of the local government of Bohai State in the Tang Dynasty in Jilin Province. It is a key cultural relic protection unit. The original name of Lingguang Pagoda has long been lost. It is said that a long time ago, when the earth's crust changed, everything overturned, only this tower stood tall, coupled with its peculiar shape, refreshing spirit, and striking people's eyebrows. Therefore, in 1908, Zhang Fengtai, the first prefect of Changbai Prefecture in the Qing Dynasty, likened it to the Lingguang Hall in Shandong during the Western Han Dynasty and named it Lingguang Pagoda. Lingguang Pagoda is built with blue-gray square bricks and is a pavilion-style hollow square tower. It consists of five parts: passage, corridor, underground palace, tower body and pagoda. Although the bricks have fallen off sporadically and the tower is slightly tilted after thousands of years of erosion by wind, frost, rain and snow, it is still as solid as a rock and towers high above the clouds. Even the fallen fragments are very hard and make a clear and pleasant sound when knocked. The passage is stepped, with a total of 11 steps.
