According to a legend, tea was first discovered by the legendary Chinese emperor Shennong in 2737 BC. Today, China is the worldโs biggest tea producer, selling many varieties of tea leaves such as green tea, black tea, oolong tea, white tea and yellow tea. It is the most highly consumed beverage in the world. China still boasts many teahouses, particularly in cities with a strong teahouse culture such as Hangzhou, Suzhou, and Chengdu. Different regions are famous for growing different types of tea. Hangzhou is famous for producing a type of green tea called Longjing or the Dragon Well tea. Tea tastes also vary regionally. Drinkers in Beijing tend to prefer jasmine tea while in Shanghai prefer green tea. Processing raw tea leaves for consumption is a time and labor-intensive activity and still done by hand in many areas in China. The Chinese tea industry employs around 80 million people as farmers, pickers and sales people. Tea pickers tend to be seasonal workers who migrate from all parts of the country during harvest time. The pickers work from early morning until evening for an average wage of around 120 RMB (around 16 euros) a day. Tea can be sold from around 80 RMB (around 11 euros) to over 4,000 RMB (around 525 euro) per kilogram. In 2016, China produced 2.43 million tons of tea. Chinese people believe that the practice of brewing and drinking tea can bring the spirit and wisdom of human beings to a higher level.

Back when he was an undergraduate physics major at the University of Havana in Cuba in 2008, Bianchi noticed something unusual while brewing a fresh cup of mateโa popular (and potent) South American tea. Preparing mate involves pouring hot water over mate leaves packed into a cup and letting them steep. Generally, things tend to flow downstream, yet he found a few mate leaves inexplicably ended up back in the kettle. Somehow, they had traveled upstream.
