According to historical records, Shen Tao, magistrate of Zhengding and author of Records of Stone Inscriptions in Changshan, discovered the epitaph of Wang Rong, Military Governor of Chengde Army of the Tang Dynasty, outside Lijiazhuang Village north of Zhengding in the 17th year of the Daoguang reign of the Qing Dynasty (1837).

From 1973 to 1979, the Hebei Cultural Relics Administration and Zhengding County Cultural Relics Preservation Institute jointly excavated three Tang Dynasty tombs at Muzhuang Village, 7.5 kilometers north of Zhengding. Only one tomb yielded a complete set of epitaphs for Wang Yuankui, Military Governor of Chengde Army, as well as the epitaph cover of Princess Lu.

In April 2007, another complete epitaph set for Wang Shizhen, former Military Governor of Chengde Army of the Tang Dynasty, was unearthed in the northwest of Yujiazhuang Village north of Zhengding during the construction of Bid Section 7 of the South-to-North Water Diversion Project. The epitaph of Wang Rong was lost in early years, while all the other relics are now preserved in Zhengding County Cultural Relics Preservation Institute.

The tomb of Wang Yuankui is situated in Muzhuang Village, 7.5 kilometers north of the county seat. It lies on a plain, adjacent to the Beijing-Guangzhou Railway on the west and National Highway 107. The tomb is located beneath the house foundation of Zhao Xiaohuan at the eastern end of Muzhuang Village. Under the guidance of Hebei Provincial Cultural Relics Bureau, the tomb was partially cleared. Due to residential buildings above ground, the entire burial chamber could not be fully excavated.

The epitaph of Wang Shizhen was discovered on April 28, 2007, in Zone 2 of Bid Section S7 of the South-to-North Water Diversion Project, north of Yujiazhuang Village, Zhengding County. Carved from bluestone, this square epitaph set was found broken into four pieces.

The cover measures 149.7 cm long, 150.6 cm wide and 36 cm thick. Its surface bears 25 seal characters in two incised lines, reading: Epitaph of Late Lord Wang of Taiyuan, Former Military Governor of Chengde Army, Censor-in-Chief, Grand Councilor and Posthumously Appointed Minister over the Masses of the Tang Dynasty.

The main tablet is 152 cm long, 151 cm wide and 29.7 cm thick. In running regular script, it consists of 40 lines with 43 characters per full line. The inscription was composed by Li Xu from Anping and written by Wang Ji from Taiyuan. Peony patterns are carved all over the beveled edges of the cover, as well as the sides of both the cover and the main tablet.

The epitaph of Wang Yuankui was unearthed in Muzhuang, and the tomb of Wang Shizhen is confirmed to be north of Yujiazhuang. Relevant evidence proves that this area is the cemetery of the Wang clan. As important tombs dating back to the mid and late Tang Dynasty, they provide tangible materials for the research on the separatist rule of the Three Military Governors of Hebei, especially the political and military conditions of Chengde Circuit.

On October 23, 2008, the site was designated a Major Historical and Cultural Site Protected at the Provincial Level by the People's Government of Hebei Province
