According to Lou and Liang Jiapu, after three years in office, when Sun Liang, the eighth ancestor of Tianzu, and Dianbang, his uncle, were both lieutenant generals, he was ordered to enter the DPRK to broadcast with General Yang Duanping, and was stationed at the black cliff in Zuntong Mountain. Later, Lou Shan, the son of Dianbang, followed in his father's footsteps and guarded the black cliff. Later, Loushan and Guan Liang were ordered to go south and set up a business in Anshun. People in Heishanya miss the friendship with Loushanguan and Guanliang garrison, so they renamed Heishanya as "Loushanguan" one by one and later called "Loushanguan".
1932, Huang Pimo (Huang Daobin), then director of the Civil Affairs Department of Guizhou Province, wrote three cursive words "Loushanguan" at the junction of Zunyi and Tongzi counties on the Sichuan-Guizhou Highway.
1985, in order to commemorate the 50th anniversary of Zunyi Conference, Zunyi County Government made a large-scale sculpture "Loushanguan" on the rocks in the northeast of Loushanguan. The word "Loushanguan" was inscribed by Shu Tong, a famous calligrapher in China. Mo Yan has a total length of 1 1 m and a word diameter of 2.3 m. The brushwork is vigorous and powerful, and the seal cutting is fiery red, which is particularly eye-catching in Xiongguan Song Qing.
