Moreover, this seemingly simple QR code contains personally identifiable information and will be marked with special colors. Green means everything is normal and you can travel freely, yellow means medium risk and red means high risk. So whether you have been to an epidemic area, whether you have seen a doctor because of illness and whether you are healthy can be identified by the color of this simple QR code. But here comes the problem. Every province and even every city has launched its own health code, and cross-provincial tourism often needs to scan several health codes. But now, the health code basically supports most parts of the country? One yard? Safe. This can greatly facilitate our travel, but during the epidemic, it is best to go out less and protect yourself.
Although this sudden epidemic has changed the production and living order of Chinese people, the Internet has shown great strength and played a key role in winning the epidemic prevention and control war. In the future, more innovative Internet applications will stand out and better serve the society and the public. I hope I can develop something simpler in the future, and I can really travel around the world with a mobile phone when I go out.
Although there is a health code, it is best to go out less during the epidemic, so as to protect your health and contribute to the management of the country. Although the world is big, happiness is small. I hope not only that spring will come as scheduled, but also that you will be safe after the epidemic. May all the good things come as scheduled!
Sometimes I have been thinking, if this epidemic is regarded as the last time in my life, will I live fast? Although my present life is definitely not what I want, what should I do and what can I do? I don't know myself. I only know that when faced with difficulties, don't shrink back, but try to look forward. Only our own strength is what we should do.
