Modern Chinese New Year's Day has become a very important festival. After the founding of New China, January 1st of each year will be designated as a statutory holiday. On this day, the New Year will be welcomed in different ways throughout the country. Although the habits of countries all over the world are not the same, on New Year's Day, people from all over the world will come up with their own unique ways to welcome the new year. The Germans can be said to pay great attention to the New Year's Day. The New Year's dinner will be very rich, because they feel that the New Year's dinner has fish and meat, which means that the whole year is full of fish and meat. In the UK, the feeling of the New Year is not as important as Christmas, but every household will have a big meal on this day and have been busy for a year. In the rural cities of central England, people will fight for wells on New Year's Day. Everyone feels that the first person in the new year to

On New Year's Day in China, the Emperor Sui, one of the five emperors from more than 3,000 years ago, was the first month of the Lunar New Year, and the first day was the New Year's Day. This is the original text of the New Year's Day name, but with the change of history, the date of New Year's Day has also been changing. Finally, after the Revolution of 1911, the first day of the Lunar Calendar was confirmed as "New Year's Day." The customs of different countries on New Year's Day are different, but the emotions expressed are generally the same, that is, the joy of family reunion. First, Bulgaria On the day of New Year's Day, everyone will find ways to sneeze, and Bulgarians believe that this can bring good luck. Second, Peru When the whole family is reunited and waiting for the stop of the zero o'clock, everyone will have the rhythm of the grapes to eat.

GPON and EPON  have their own advantages. GPON is better than EPON in terms of performance indicators. However, EPON has the advantage of time and cost. GPON is catching up. Looking forward to the future broadband access market may not be a replacement, it should be complementary. For bandwidth, multi-service, high QoS and security requirements, and ATM technology as a backbone customer, GPON will be more suitable. For customers with low cost sensitivity, QoS and security requirements, EPON has become the dominant factor. What is PON? The PON (Passive Optical Network) is the main technology for implementing FTTH fiber-to-the-home. It provides point-to-multipoint fiber access. It consists of the OLT (optical line terminal) on the office side and the ONU (optical network unit) on the user side) and ODN (Optical Distribution Network).

According to media surveys, an advertising marketing device with WiFi probes as the main technical means has quietly emerged. Such devices collect user information by acquiring the user's mobile phone Mac (Media Access Control) address. Some devices can force the user's mobile phone to pop up the window, and pretend to be connected to WiFi on the WeChat top interface to deliver "dog skin plaster" ads that cannot be eliminated. WeChat said that it has monitored such malicious deception and has responded technically to the monitored situation. The WiFi probe is suspected of infringing on the privacy of users and should be severely punished according to law. In addition to the network platform to assume responsibility, the regulatory authorities should also slash swords in time to protect personal information and build information security barriers.
