[Opening] The epidemic in Shanghai yesterday was 1+0-0. It is not easy to clear this single item. I feel that there are many people who are given red codes now, and they are all the result of close contacts among children at Disneyland. However, even if there are people who have been blocked from all directions, there are few cases, which shows that Disney has done a good job in epidemic prevention and control, and Shanghai’s anti-epidemic work is still very solid. Many areas have implemented temporary control measures, suspended non-essential mobility, and screened personnel and the environment. It is said that nucleic acid was screened for 442,000 people in related control and isolation, and the nucleic acid test results were all negative. I saw a saying that the virus survives in the lungs and throat of the human body, and it is better to rinse the mouth with hot salt water to disinfect the virus.

[Get the headlines] two topics. First, the revenue of fuel vehicle repair masters has declined, and second, high-end bottled water is competing for the market.

first item. Recently, there was something wrong with the author's car at home. I went to repair the car and chatted with the repairman. The master sighed and said that their industry is getting harder and harder to do, and the overall income is declining. Many people still have to take on the job of a designated driver to subsidize their family income after get off work. After asking, I found out that it was caused by 's new energy vehicle . First of all, compared with fuel vehicles, the maintenance of new energy vehicles is simpler, and conventional maintenance projects such as engine oil , three-filter , belts, etc. are all saved; secondly, many functions of new energy vehicles are controlled by software, and manufacturers do not allow repair shops to casually repair, just like Apple phones do not open to third-party repairs; thirdly, traditional fuel vehicles are mainly machine-based, and when repairing new energy vehicles, you must be proficient in circuits, be able to use software to calibrate sensors and cameras, and even program them. In the past, the repairman used to repair the car with an wrench and , but in the future, it is likely that he was repairing the car with a tablet computer.

second item. Recently, the high-end bottled water market has been very lively. First, SmartWater, a brand under Coca-Cola , announced its entry into the Chinese market. It has been listed on the Sam membership store in Beijing, Shanghai and other cities; then Taihe Water, a listed A-share , announced that it will enter the high-end drinking water market, planning to acquire more than ten high-quality water sources in the next 3-5 years, and also use "photosynthetic kinetics" technology to produce super small molecule water . This is the rhythm of letting us drink high-tech water. More and more companies are focusing on high-end bottled water. The reason is simple, it is too profitable. For example, a bottle of Tibet 5100, which costs more than ten yuan, has a gross profit margin of over 81.2% at its highest, which is higher than , Wuliangye . Nongfu Spring Driven by high-end products such as tea making and baby water, the overall gross profit margin of bottled water is also around 60%.

[The future is whistling] Elon. Musk's main residence in Los Angeles is located in Bell Air, nearly 30 km from SpaceX's office in Hawthorne. His commute time is around 35 minutes at best. But December 17, 2016 (which happened to be the anniversary of the first flight of the Wright Brothers ) was not a good day. Highway 405 was completely blocked, and the car that was motionless and invisible at a glance drove Musk crazy. However, this also gave him time to post Twitter, which recorded his idea of ​​establishing a ' hole company '.

Musk did in the end. Eight months later, on July 20, Apollo Moon Landing, Musk announced on Twitter: "I just received verbal approval from the government that our burrowing company will build an super high-speed rail underground, with the driving route being New York Philadelphia Baltimore Washington . New York to Washington, 29 minutes." In the spring of 2018, Musk took out $113 million to start the burrowing company. It is said that only a 1.29-kilometer tunnel was dug, and cars can drive quickly in the tunnel, which probably has no practical value.
