The legacy of Japanese national treasure actress Xilin Tree is adapted from the book "every Day is the 15 kinds of Happiness brought by ─ Tea ceremony" by Moriko Morishita, a professor of tea ceremony. To the college student Dianzi (Kuroki Hua) who is confused about his future, he learns the tea ceremony from his cousin Miyoko (many parts of Weihuazi) to the rigorous Takeda teacher (Shimi Xilin). At first, Dianzi knew nothing about the tea ceremony, but he gradually realized that "form first and then heart" and "bear a heavy burden as if light" and so on. The tea ceremony silently accompanied her through many times of spring, summer, autumn and winter. After going through all the important stages of her life, she gradually realized the true meaning of the calligraphy and painting "every day is a good day" on the walls of the teahouse. Although the person has gone, the tea is not cold, the tree Xilin finally sent us a bowl of warm tea full of philosophy of life, endless rhyme.
