The idle Process

On Feb 25, 2020, Alibaba's Alipay epidemic real-time tracking page suspected to show a bug. Once opened Alipay on the phone, the page shows the infected data was 77,785 and the number of suspected cases was 20,200,340. If so many suspected cases did occur, it could on be that there are other big cities have an outbreak, but till now there is no such news.  The bug seems to it wrongly take the date to be the suspected number. 2020 stand for the year, 03 means March. Only 40 could be not explained, could be inverse of 04.

To say that this new virus is far more infectious than SARS is based on the following three facts: First, the infected person does not have any symptoms during the incubation period of 10-14 days. Currently, airports, stations, and terminals are all measured with fever, but most of them are ineffective. This is why a city such as Shanghai, which is extremely well guarded against high fever persons, but there still emerge a large number of confirmed and suspected patients. Second, and equally frightening is that this latent virus carrier does not have any symptoms himself and don't develop, but it is highly contagious.  Third, the virus is not only transmitted through breathing, but may also be transmitted from the eyes by close contact with people who carry the virus. Therefore, strictly speaking, the tightest protection is not only wearing a mask, but also goggles . However, in fact, very few people in the hospital waiting for a crowded consultation are wearing goggles .

Why are you so focused? It turned out that the pelicans were all waiting to eat fish with their heads up, hahahaha! In the Central Coast area north of Sydney, there is a beautiful and famous town called The Entrance, which has the title of "Australian Pelican Capital". What makes a town so honored? The reason is these cute toucans. Every afternoon, the pelicans fly here from near and far, and there are no obstacles 365 days a year. As soon as 3:30, a staff member will push a large box full of fish to the small square where the pelicans gather, and the pelicans have long been eager to wait. This white-haired grandpa came to feed today. I saw the grandfather skillfully put on rubber gloves, while taking a fish out of the box and throwing it at the pelican, he interacted with the onlookers and introduced the knowledge of the pelican. The noise of the pelicans competing for the fish and the exclamation of the onlookers crowded into one, the atmosphere was warm. A clever pelican s
