Introduction to the main hall: A statue of Zhuge Liang sits on the shrine in the middle of the main hall, with a piano boy and a book boy standing beside him, holding a sword and a seal ribbon. Under the niche, Guan Xing and Zhang Bao were guarding him. The four large regular characters "Zhongguan Yunxiao" on the blue background and gold plaque above the shrine indicate that in the eighth year of Jiaqing in the Qing Dynasty (AD 1803), the emperor received Yan Yu's letter to the palace and "post-posted" to Mian County, where the imperial envoy from the Ministry of Industry came to Mian The county representative emperor hung the plaque here. There is a couplet on both sides of the gate: "The Central Plains has not yet been settled, how can this soul return to its homeland? I will cherish Western Shu forever, and I will die with hatred and bury the army." This couplet expresses Zhuge Liang's ancient regret when he died.
