"Dian Cha" is a unique cultural symbol of the Song Dynasty (960-1276). Tea masters whipped the mixture of water and ground tea leaves with a bamboo brush until it became foamy. Someone is making Dian Cha in the deep tea garden, and Su Xiaomei smelled the wonderful scent. She could not help but walk over. Do you want to try this full cup of foam? CGTN is launching the "Cup of Tea" challenge to celebrate the 10th anniversary of the China-proposed Belt and Road Initiative. Come and join the challenge with Su Xiaomei!
