China facts of the day

The Economist has these figures on the Chinese appetite for lifts,
In 2000 some 40,000 new lifts were installed in the country. By 2016 the number was 600,000—almost three quarters of the 825,000 sold worldwide. China not only wanted more skyscrapers; it wanted taller ones. More than 100 buildings round the world are over 300 metres; almost all of them were built this century, and nearly half of them in China. The country is home to two-thirds of the 128 buildings over 200 metres completed in 2016. Other countries may content themselves with a few show-off pinnacles. China buys them by the dozen.
This is a fascinating (and disturbing) account of how Chinese digital companies are using personal data to score a person's social credit and offer the full spectrum of services covering the daily lives of Chinese. Sample this,
Alipay knows that at 1 pm on the afternoon of August 26, I rented an Ofo brand bike outside Shanghai’s former French Concession and rode north, parking it across from Jing’an Temple. It knows that at 1:24 pm I bought a snack in the mall next to the temple. It knows that afterward I got in a Didi car bound for a neighborhood to the northwest. It knows that at 3:11 pm I disembarked and entered a supermarket, and it knows (because Alibaba owns the supermarket, which accepts only Alipay at checkout) that at 3:36 pm I bought bananas, cheese, and crackers. It knows that I then got in a taxi, and that I arrived at my destination at 4:01 pm. It knows the identification number of the taxi that drove me there. It knows that at 4:19 pm I paid $8 for an Amazon delivery. For three sweet hours—one of which I spent in the swimming pool—it does not know my whereabouts. Then it knows that I rented another Ofo bike outside a hotel in central Shanghai, cycled 10 minutes, and at 7:11 pm parked it outside a popular restaurant. Because Ant Financial is a strategic investor in Ofo, Alipay might know the route I took.
