Running an electric appliance company sounds simple, but it's really not that easy.
Some focus on the market, some on branding, and others on key components of the entire system.
Key components might not have high technical content, nor are they impossible for others to produce; the core issue is cost calculation. Only by well-integrating upstream and downstream channels, transportation, labor, and mechanical costs can you achieve price competitiveness.
In other words, other companies could do it, but without forming a price advantage, it's better not to do it.
Take the ballpoint pen tip for example, Huaxia could produce it, but since specialized foreign companies are doing it, and there's only one company globally, when Huaxia produced dozens of tons, that company sued instead.
