Lin Yan opened a small teahouse in an old alley, making tea and reading books, and lived a leisurely life. No one knows that this woman with gentle eyebrows has been here for two thousand years. She experienced the blood of Changping, saw the music of the piano in Longzhong, watched the fireworks while drunk, and caught a glimpse of the Queen's youth. From bright clothes and angry horses to feather fans and silk scarves, from farm farmers to teachers, we have witnessed the changes of dynasties, and finally, thousands of years of stories are hidden in the tea smoke, and we can spend time quietly.
