Weng Zhong, formerly known as Ruan, was a Hercules during the Qin Shihuang period. According to legend, he is 1.3 feet long and has extraordinary courage. Qin Shihuang ordered Weng Zhong to guard Lintao, which is a great example of Xiongnu. After Weng Zhong's death, Qin Shihuang cast a bronze statue for him and placed it outside Sima Gate of Xianyang Palace. When Huns came to Xianyang, they foresaw the bronze statue and thought it was really Ruan, so they dared not go near it. The origin of Weng Zhong began with twelve bronze statues cast by Qin Shihuang. "Historical Records of the First Qin Emperor" said that in the twenty-sixth year of Qin Shihuang, "the soldiers in the world gathered in Xianyang and sold them as Zhong Kui and Ren Jin, each weighing thousands of stones and placed them in the palace." Justice quoted Three Volts and Nine Stones and Water Mirror He Zhushui (IV), all of which were called "Weng Zhong" because each bronze man weighed 240,000 Jin.
Ruan Weng Zhong not only appeared in Qin Shihuang Mausoleum and Wu Zetian Gan Mausoleum, but also appeared in many other royal tombs.
Sima Zhen's Historical Records says, "Each weighs a thousand stones and sits two feet high, so it is called Weng Zhong." It can be seen that the pre-Weng Zhong of the mausoleum began in the Qin Dynasty. Weng Zhong Road is the only way from Zijin Mountain to the Ming Tombs. There are four pairs of stone statues on the road, two pairs of civil servants and military commanders. Civil officials and military commanders are solemn and solemn, symbolizing the literary martial arts of the underworld after the death of the emperor. Weng Zhong in Ming tombs is as high as 3.18m, which is said to be the highest Weng Zhong.
