Japanese tea ceremony
The Japanese tea ceremony (called cha-no-yu, chado, or sado) is a special way of making green tea (matcha 抹茶).  It is called the Way of Tea. It is a Japanese cultural activity involving the ceremonial preparation and presentation of matcha, powdered tea. People who study the tea ceremony have to learn about different kinds of tea.  They also have to learn about kimono (Japanese clothes), flowers, and many other things. It takes much practice to learn the tea ceremony.
