Who really came up with China's 'four new inventions'?
Claim: China invented high-speed rail, mobile payment, e-commerce, and bike-sharing.
Reality Check verdict: China did not invent any of these technologies - but it has led the way in their widescale implementation.
This is a claim that has repeatedly come up in Chinese state media since May 2017.
It was most recently repeated at China's National People's Congress (NPC) by Pony Ma - an NPC delegate who's better known as the chief executive of the Chinese internet giant Tencent. He's also the richest man in China, according to the Hurun Global Rich List.
"We have a new phrase called the 'new four great inventions' in China, including high-speed railway, online shopping, mobile payment and sharing bikes," he told journalists at the NPC.
But these technologies did not originate in China and were first devised decades ago.
Where did the claim come from?
The provenance of the claim appears to be a Beijing Foreign Studies University survey from May 2017, which asked young people from 20 countries to list the technology they "most wanted to bring back" to their country from China.
The respondents' top answers were high-speed rail, mobile payment, bike sharing, and e-commerce.
Since then, Chinese media and officials have drawn on this to promote these technologies as China's "four new great inventions" in modern times.
Why keep making the claim?
The term "four new inventions" harks back to the "four great inventions" of ancient China - papermaking, gunpowder, printing and the compass.
China has been putting strong emphasis on technological advancement as it seeks to become what it calls an "innovation nation" by 2020.
"After years of subordination to the technological supremacy of developed nations in the West, China has come to realise the importance of developing core technologies on its own. Only by doing so can it truly gain independence and win respect from both partners and competitors," the Xinhua news agency says.
Already, China is the second-largest spender on research and development after the US, accounting for 21% of the world's total of nearly $2 trillion in 2015, according to the World Economic Forum.
There is no standardised definition of what constitutes "high-speed rail." The European Union defines "high-speed" as at least 250km/h (155mph) on new tracks, and 200km/h on older tracks.
According to the Worldwide Rail Organisation (UIC), the first high-speed train service began in 1964 - Japan's Shinkansen or bullet train.
There had been significant speed records set before in Europe - in France, a train reached 331 km/h in 1955 - but the Tokyo to Osaka line was the first regular service to travel that fast - the first trains had a maximum speed of 210 km/h.
China opened its first high-speed rail line in 2008, from Beijing to Tianjin, just ahead of the Olympic Games.
Some of the first payments by a mobile device were made in 1997 in Finland.
Local news reports from the time (in Finnish) stated that Telecom Finland had enabled a music jukebox and drinks vending machines to be operated by calling a payphone number - including Coca-Cola machines in Helsinki Airport.
However, some argue that mobile payment technology truly began when Apple Pay made its debut in 2014.
Using a technology called Videotex, Mr Aldrich connected an ordinary TV set to the local retailer's computer via a telephone line.
But it wasn't until the 1990s that e-commerce became popular, when Amazon and eBay launched their websites in 1995.
Lastly, the first bike-sharing concept - called the "white bicycle plan" - was introduced in Amsterdam in the 1960s by the Dutch counterculture movement Provo. However, the bikes were confiscated by the police in case they encouraged theft.
The first large-scale bike sharing schemes began in the 1990s in European cities - Copenhagen is credited with introducing the first.
But Chinese firms like Mobike and Ofo are at the forefront of "dockless" bike-sharing, a new system where users locate bikes with their smartphone, and drop them off anywhere without the need to park them at a specific dock.
Likewise, China has outpaced other countries in the widespread adoption and adaptation of all of the four technologies.
"Some may argue that the technologies the 'four new great inventions' are based on did not originate in China. That is true, but it is China that used the technologies to come up with the new inventions," writes Xu Gongcheng, a professor at Xiamen University.
China now has the world's largest high-speed rail network - about 25,000 kilometres (15,500 miles) - and aims to double it by 2030.
China's total mobile payments in the first 10 months of 2017 stood at $12.7 trillion, the world's largest volume, according to China's Ministry of Industry and Information Technology.
And with more than 700 million internet users, China is also the biggest and fastest growing e-commerce market in the world, according to a 2017 study by PricewaterhouseCoopers.
In February, the vice minister of China's Ministry of Transport said that there are 400 million registered bike-sharing users and 23 million shared bikes in China.
