How and where is audio equipment manufactured and assembled in China? I visited the Penhui factory!

Описание: Quite by chance, I met Mr. Zhao in China, who turned out to be the founder and owner of a very respectable and long-established manufacturing company that produces various types of audio equipment, amplifiers, and processors for both home and car use. The report was filmed by hand, so after watching it, you will essentially be able to visit this factory with me and see how medium-sized businesses operate in China.
