On March 15, according to the clues provided by the whistleblower, the reporter came to the Kede International Hardware Market in Nanning in January 2025. The reporter found in the market survey that the price of wire and cable products sold by some merchants here is obviously low, and the rhetoric is basically the same, that is, they are selling so-called "non-standard wire". Simply put, the so-called "non-standard wire" is the wire and cable that does not meet the national testing standards. In this market, the sale of "non-standard discounted wire" is no secret. Guiyang's Jinshi Hardware and Electrical City is one of the larger hardware trading markets in South China. However, some merchants are also selling cables of the same specification and two prices. According to the statistics of the Ministry of Emergency Management, in the case of major fires in China, fires caused by cables account for more than 50%, ranking first among all types of fires. In the past ten years, there have been more than 100 major accidents caused by cable fires and disasters across the country.
