No, the BSL-4 lab in Wuhan contributed absolutely nothing to help during the outbreak of the disease. The analysis on the samples and the gene sequencing were all performed in Shanghai, by various institutions such as Institut Pasteur of Shanghai, or the Chinese Academy of Science (e.g. see the list of authors in paper [0]), not in Wuhan at all - Which was an already huge surprise to everyone following the news in China, considering the fact that it has one of the best labs.

Although the exact reason is unknown, it is already known that the Wuhan government has successfully implemented the maximum level of incompetence during its early response. There is no much reporting in English yet, but a now-deleted government report in Chinese [1] said the first victims of the viral infection were already been hospitalized on as early as December 8th, 2019. In other words, they were given a time of three weeks to get useful things done. Yet, the Wuhan government took no actions whatsoever other than covering up the outbreak.

It had been going on like that, until the last week in December, when the news about a new type of unknown pneumonia started to leak out. At this time, someone at a higher position probably realized a serious investigation was warranted. On December 26th, researchers from Shanghai arrived, collected samples, and brought the samples to Shanghai for analysis [4].

Meanwhile, on December 30th, the case was escalated and put under increased supervision of the national government. And On December 31th, a Wuhan government official was interviewed [2]. He was asked for whether a laboratory analysis will be started, and the reply was,

> With regarding to the pathogen determination of the unknown pneumonia, currently, the BSL-4 Lab was not activated, we are still following conventional procedures to verify the cases of infection. We are always prepared to active the Lab accordingly when it is necessary.

> So far, it is not in our considerations.

So Wuhan, still, wasn't doing any analysis at this point. Well, they have other things to do. On January 1st, Wuhan police arrested 8 citizens for spreading the "false rumor" of outbreak of a mysterious pneumonia in Wuhan to the social media online.

Later on January 7th, 2020, the first laboratory observation [3] of the virus sample under the electron microscope came out from Shanghai. And the gene sequencing was only completed in the second week of the month. [0] I guess the Shanghai labs were probably working on a 24x7 basis.

Meanwhile, Wuhan ordered a partial travel ban, only at this point - without any preparation work, Wuhan suddenly suspended the public transport for everyone, including medical workers, creating a massive chaos.

The popular belief is: The fact the analysis was performed in Shanghai is another indicator of the Beijing government's effort to bypass the provincial government to obtain real information. According to what Wuhan has done, it's possible that the Wuhan government was intentionally withholding medical samples and hampering the BSL-4 lab to do any useful work, and that Beijing didn't even receive prompt information until the last moment.

What is the lesson to learn as a citizen? Never overestimate the effectiveness of an authoritarian government, and never underestimate its incompetence. In an authoritarian government, the best interests of the ruler at a higher level is not always served by the ruler at the lower level. Sometimes, it's Nineteen Eighty-Four, other times, it's Brazil.
