You may have seen a barista （咖啡师） pour milk foam（奶泡） into a coffee，then you can see a beautiful pattern（图案） .But have you seen the art in a cup of tea？
    Dian cha is a tea at from the Song Dynasty.The art begins with pouring water over fine powdered （粉状的） tea，creating a paste （糊） and then adding more hot water，whisking （搅动）it by hand with a bamboo whisk It is believed that the art later spread to other parts of East Asia，including Japan.In 2019，it was listed as an intangible cultural heritage （非物质文化遗产） of Runzhou district Zbenjiang city，JiangSu province.
    The Shanghai designer Han Zhemin has been interested in dian cha since childhood. "My mother loves traditional culture and I have been influenced，" said Han.After he graduated from the China Academy of Art in Zhejiang province in 2006，Han tried his best to reviving（复兴） the art form.
    He said during the process of dian cha，the froth （泡沫） tried his best to paper while he tea paste is like ink.But "drawing" on the tea foam is not easy. "Traditional paintings is about the soft brush against the hard paper，but the tea is about the bard teaspoon and the soft froth." Han said.
    Creating patterns on the tea foam is careful but quick work.Usually，the whole process has to be completed within 10 minutes.The ideal state is when the tea's temperature is around 40 C and ready for the palate （味觉）. "Usually，it takes a year of practice for one to be able to do it" Han added.
    To spread dian cha culture，Han put the process of tea whisking and drawing on social media platforms，including Xiaohongshu，Bilibili and Douyin，attracting more than 20，000 followers.When taking about tea art Han said we should increase the beauty rather than change the essence（本质） of tea. "I want more people to understand the processes and reasons of tea making" he explained.
