On April 15, 1990, a 4-year-old boy named Tang Jiang from Xiangxiang, Hunan Province, suddenly experienced an incident of human combustion, drawing widespread attention. That morning, flames erupted from his pants, burning through three layers of different materials, while his feet also showed signs of burns. Initially, doctors diagnosed it as an allergic static electricity reaction, but shortly after returning home, a fireball reappeared on his thigh, causing severe burns. Ultimately, the child was taken to the affiliated hospital of Hunan Medical University in Changsha for detailed examination, which revealed that his body's electrical current and resistance were significantly higher than those of normal children, yet the exact cause of the combustion remains to be further studied.

This rare phenomenon not only perplexes but also ignites curiosity about the unknown realms of science. Is it static electricity or some other mysterious force at play? This case of human combustion remains an unsolved mystery to this day.
