Li Mao is the site of the Battle of Crossing the River during the War of Liberation. At the top of the mountain overlooking the Yangtze River, there are trenches on the mountain, which were left behind during the battle of crossing the river. In order to remember the great achievements of revolutionary martyrs and inspire future generations to work hard to revitalize China, Tongling Civil Affairs Department built a memorial tower at the top of Li Mao on 1958, named Tongling Martyrs Tower. The tower is a reinforced concrete structure, covering an area of 900 square meters, with a building area of 400 square meters and a tower height of 30 meters. There is a rest platform with handrails in the middle of the tower. On the platform, you can see the Yangtze River and the county seat. The tower is a three-story square solid tower, with sixteen characters engraved on the east, south, west and north respectively, such as "bright sun and moon", "majestic mountains and rivers", "immortal" and "everlasting". Written by Zhang, the former chairman and calligrapher of Anhui, it is solemn and magnificent. Surrounded by lush flowers and plants, pine and cypress stand upright.
