Fake, unreliable. First, Chinese names are the same as well-known brands, but they are followed by English, but the English letters are different. For example, people in China who are not sensitive to letters are really stupid. The second type is more subtle, and the small print is directly added after the well-known brands, but the small print also has some connection between products, such as Skyworth Smart, Skyworth Shang Zhi, Zhongshan Duckling, Xinfei Technology and Konka Vision, which I thought were the series names of well-known brand products.
