The high-end LiFi visible light communication technology has long been used by the ancients?

If you travel back to ancient times, what is the most unbearable thing for you? Presumably most people will say: "No WiFi!" For modern people, life without fast information is simply unimaginable. However, many film and television dramas also tell us that when there is no WiFi, there are still many ways to quickly transmit information, such as lights. In the period film "Twelve Hours in Changan", the lookout tower of Changan City uses 12 squares to transmit information. Each square can be lit or extinguished with a light. There are as many as 212 permutations and combinations, representing a variety of different information, or can be said to transmit 12 bits of information. Is this method really reliable? Did the ancients really use these methods to communicate? In the absence of mobile phones and the Internet, is the artificial way of sending messages in the two films true?

What is the average age of Chinese Lamborghini owners?

36 years old is the average age of Lamborghini owners in China. In fact, before Lamborghini officially delivered the SUV model Urus, this average age was even younger.

Just after midnight on Friday, July 31st, a subscription channel called Todd Capital Options Community in the Slack community was buzzing. The $20-a-month channel was popular with thousands of options newbies. Unemployment in the United States soared during the epidemic, and the government was desperately trying to prevent the economy from collapsing. But the channel members were partying all night, and it was no exaggeration to say that this was like 1999, the height of trading before the dot-com bubble burst in March 2000. Despite the epidemic, Amazon, Apple, Facebook and Google all released eye-popping financial results. At a time when U.S. gross domestic product was plummeting at a rate of 33%, these technology companies' combined revenue for the quarter reached
Why are there no high-end shopping malls in Chinese university towns?

Why are there no high-end shopping malls in Chinese university towns?

After the epidemic, the integration of industry and city based on university resources is becoming the focus of local policies again, and the development of commercial incremental projects and the operation of existing projects in the construction of corresponding new cities are gradually returning to the right track. However, for many young people, the commercial facilities around the university town are always unforgettable memories. In Stanford University, a famous Ivy League school, there is a large-scale high-end shopping mall with Hermès and LV, which radiates to Stanford University Town and even the entire Silicon Valley. Even, for a long time, this shopping mall has been independently operated and managed by the school. In this issue, we start from the case of Stanford Shopping Center to rethink the business logic and innovative strategies of domestic university towns. First, high-end businesses can also enter universities. How did Stanford do it?
