In the process of excavating ancient tombs, experts often discover various precious cultural relics. Cultural relics are not only cultural inheritors, but also historical narrators. 1988, a "strange" bronze lamp was unearthed from the Heimajing Han nationality in Gejiu, Yunnan, which reflected the wisdom of the ancients.

According to relevant records, bronzes first appeared in the two river basins 6000 years ago. After the development of the dynasty, the technology of making bronzes gradually matured. During the Eastern Han Dynasty, bronze technology reached its peak, with unique design and exquisite utensils.

Three-figurine bronze lanterns unearthed from Heimajing Han Tomb in Gejiu, Yunnan Province are bronze works with a strong sense of science and technology. In feudal society, due to the limitation of technical conditions at that time, when bronze wares were damaged, it was difficult to restore them to their original state even if they were repaired. In order to solve this problem, craftsmen invented the method of casting in a separate mold, and they divided the bronze ware into parts for firing. If a part is broken, they can replace it directly without abandoning the whole. In modern terms, it is "modular production".

"Three bronze lanterns of the Eastern Han Dynasty" proved that the technology of dismantling "humanoid hand-making" in the Han Dynasty was mature and applied to bronze ware making. This cultural relic shows us the glory and achievements of bronze culture in Han Dynasty, and provides detailed material evidence for future generations to study modular bronze manufacturing technology.
