Zhu Youyi

Prince Gong of Luoshan, Zhu Youyi (1409–1429), was an illegitimate son of King Ding of Zhou, Zhu Su. He was bestowed the title of Prince of Luoshan. In the second year of the Xuande reign (1427), he was officially granted the title of prince, and he died in the fourth year of Xuande (1429), with the posthumous name "Dao Gong." His wife, Madam Zhang, committed suicide and was buried with him after his death. Due to having no children, the Ming Dynasty revoked the title of the Luoshan Kingdom.

The tomb of Prince Luoshan and his wife is located at the west of Baimuguan Village, Fancun Township, Kaifeng County, at the bottom of a dried-up fish pond. According to archaeological surveys, the tomb comprises the tomb chamber, tomb passage, spirit way, corridor, and tomb enclosure, covering an area of approximately 12,000 square meters. The tomb chamber consists of front and back sections connected by an archway, forming a vaulted structure. The excavation covers about 150 square meters; the tomb chamber measures 12.8 meters in length, 7.2 meters in width, and 2.9 meters in depth, totaling an area of approximately 92.16 square meters.

Due to multiple looting and flooding, the tomb has suffered severe damage, with only remnants of early tomb structures remaining, and the tomb chamber has collapsed. No burial objects were found; however, a large number of Ming Dynasty architectural components, ceramic shards, pottery fragments, ironware, as well as some Han Dynasty ceramics and coins were unearthed. Among the artifacts, there are exquisitely crafted glazed tiles featuring dragon patterns with water droplet shapes, green-glazed dragon-patterned tube tiles, and complementary animal ornaments, which hold high artistic and craft value.
