Today, 35 years ago, on September 15, 1990 (Lunar Calendar July 27, 1990), the domestic visual telephone was first opened in Beijing, China. On the eve of the Beijing Asian Show, China's first visual telephone business was opened between the Beijing International Telecommunications Window and the Shanghai International Telecommunications Bureau on September 15, 1990 in Beijing City Telecommunications Bureau. The domestic visual telephone is a double-effect of the image of both calls and visible calls, which is a more advanced means of communication than the general telephone business. During the Asian Games, the Asian News Center set up a visual telephone for Chinese and foreign journalists to use. Currently, the international visual telephone business is available directly to Japan.
