When the client SYN packet arrives at the filter gateway, the SYN agent does not forward the SYN packet, but actively replies the SYN/ACK packet to the client in the name of the server.

The phenomenon of accelerated death of cancer patients due to surgical treatment has further aroused people's fear of cancer. Nowadays, most people do not die of cancer, but of psychological fear. Therefore, we must, like the United States, carry out a large-scale publicity that cancer is a chronic disease. First of all, by solving this psychological disease well, we can reduce the mortality rate of cancer patients in our country-after all, it is the first to save lives. Every year there are 2.2 million people with cancer in our country, and 1.6 million people are killed in a year. If each person pays 100,000 yuan for treatment, the country spends 1600 trillion yuan on cancer treatment every year. We built many magnificent hospitals in exchange for 1600 trillion and 1.6 million lives. The country pays a lot of foreign exchange to buy medical equipment for cancer treatment. Many people have lost their homes and given birth because of the treatment of cancer.
And what Wang Zeduan said about him, Liu Guangyuan, who provided oral memories earlier, He was the only survivor of the four soldiers who had rebuilt the minefield at that time. In the memory just now, He has been blaming himself for running back alone as the first-line witness of that year but failing to save his comrades.

I respected his request, so I didn't urge him to ask, and I didn't record the information about this period of history from Liu Guangyuan's perspective. It was still regrettable from my heart, but fortunately, Wang Zeduan's memory filled the gap to a large extent.

Then, analysts or sometimes decoders decode the information so that military leaders and strategists can improve their attack plans to ensure maximum attack power.
