4．By drawing patterns on the surface of a cup of tea，chabaixi，an ancient Chinese tea trick shown in a recent TV drama，has
gone viral for its similarity with modern latte art （咖啡拉花藝術(shù)）.Zhang Zhifeng，a practitioner of chabaixi，was glad to see the TV drama brought the technique（技藝） to people's attention.
Chabaixi can create endless patterns，such as bamboos and mountains or even Chinese characters.How can it be made？There are over a dozen steps，from grinding（磨碎） tea for fine powder，to pouring boiled water，stirring the mixture for thick froth（泡沫），and finally drawing the patterns.It is different from making latte because people use clear water as the object to put into the cupnstead of milk.When the water touches the surface，it turns into a white color and disappears in 20 minutes.The process before the drawing is known as the tea-making technique，diancha.The quality of diancha is extremely important to whether patterns can be successfully produced later.
"Chabaixi is one of the countless forms of tea-making techniques in China.This technique is not only unique in the world，but also it gives us a window into people's lifestyle in the Song Dynasty，a period of time when free-time activities in some ways were like what we have now，"Zhang said.
Before chabaixi was discovered by TV audiences，the technique was on the List of Intangible Cultural Heritage （非物質(zhì)文化遺產(chǎn)名錄） of Fujian Province in 2017，after it was recovered by Zhang Zhifeng.He started researching chabaixi in the 1980s and brought the technique back in 2009 after decades of practice.
Zhang considers all his hard work worthwhile.Now with Zhang's better skills in tea making，he is also performing and teaching chabaixi in vocational schools across China."About ten years ago，this special technique was close to disappearing completely.However，it is important to the tea culture，and it would be a shame to let it fade.It is my duty to pass it on to the next generations." Zhang said.
