It is about the allusion of Yue Fei
This is the couplet on the Yue Fei tomb behind the kneeling statue of Qin Hui: "The green mountains are fortunate to bury loyal bones, and the white iron is made of innocent people."
Loyal bones refer to the bones of Yue Fei
Ningchen refers to the treacherous ministers Qin Hui, Zhang Jun, etc.
Yue Fei was the main general who fought against the Jin soldiers in the early Southern Song Dynasty, but he was defeated by Qin Hui, Zhang Jun and others. He was falsely accused of rebelling against the imperial court on "unfounded" charges and framed to death. Before Yue Fei was killed, he wrote on his confession "The sky is clear, the sky is clear". After Yue Fei was killed, jailer Kai Shun risked his life by carrying Yue Fei's body across the city wall and buried him hastily next to the Jiuqucong Temple. 21 years later, Emperor Xiaozong of the Song Dynasty ordered Yue Fei Zhaoxue, and offered a high price of 500 guan to retrieve Yue Fei's body. It was moved and buried at the foot of Qixia Ridge with a grand ceremony, where Yue Fei's tomb is now located.
In the fourth year of Jiatai (1204), that is, 63 years after Yue Fei's death, the court posthumously named him King of E. The side hall, Qizhong Temple, was originally dedicated to Yue Fei's parents, but is now an exhibition room for Yue Fei's history of resisting the Jin Dynasty.
Yue Tomb, also known as Yue Tomb. After Yue Fei was killed, jailer Kai Shunqian carried his body and buried it at the foot of Beishan. After Song Xiaozong came to the throne, he was reburied here with ceremony. There is the "Jingzhong Bai Pavilion" at the entrance of the cemetery. On the north wall of the pavilion, there is a stone inscription "National Hero" written by Feng Yuxiang. Entering the cemetery gate, there are stele corridors on both sides, displaying 125 stone stele from past dynasties. The north corridor contains Yue Fei's poems, memorials and other handwritings; the south corridor contains inscriptions written by celebrities in the past dynasties and the Yue Temple was rebuilt several times. The current Yue Fei tomb was designed in the Southern Song Dynasty architectural style when it was renovated in 1979. The stone tigers, stone sheep, stone horses and stone Wengzhong displayed on both sides of the tomb passage are relics of the Ming Dynasty. Under the tomb, there are four iron figures with hands cut behind their backs and kneeling facing the tomb. They are Tai Hui, Wang, Zhang Jun and Wanqi Mao who framed Yue Fei. There is a couplet on the tomb gate behind the kneeling statue: "The green mountains are fortunate to bury loyal bones, and the innocent white iron casts sycophants."
