VCD: Few people know that the first VCD in the world was produced by Anhui Wanyan. The founder used the most advanced image decompression technology at that time to synthesize video and sound on a Zhang Xiaoguang disk, and made the first decoding prototype, which caused a great sensation in China. Some media asserted that "this may be China's only leading opportunity in the consumer electronics industry."
However, the good times did not last long. Almost all the 1000 machines produced by Wan Yan have been bought by major electronic companies. With the advantages of technology and capital, China consumer electronics market continues to be a battleground for major foreign companies. It was not until a few years later that the shanzhai mobile phone rose that it recovered slightly.
In today's world, the development of science and technology in many western countries is much faster than that in China. In such a big environment, many people will easily misunderstand. I think some things that we often use in our life now, I think they were invented by foreign countries. But in fact, from the source, we can find that these things were originally invented by China.
