Zhongwei Electronics announced serious abnormal fluctuations in stock trading. The current core technology and products of the company and its subsidiaries do not involve humanoid robot technology and products, and have not recently engaged in technical research and business layout related to humanoid robots. Inspection robots produced by the company's subsidiaries fall into the category of special robots. Their main customers are coal mines and tunnels. Their business revenue accounts for a small share of listed companies' consolidated statements, and has been in a state of loss for the past three years. Limited by relevant industry policies and market demand, their business scale is not expected to change significantly in the near future, which will have little impact on the overall performance of listed companies.
