"Picking up flavor diary" is a story about Jiang Chen, an exchange student from Taiwan, who came to Xikou of Fenghua to find a familiar flavor with the thoughts of his hometown and the wishes of his ancestors. It's a journey from the tip of his foot to the tip of his tongue. The film revolves around Nostalgia on both sides of the Strait. Thousand layer cake is not only a kind of food, but also a carrier of nostalgia. It carries the nostalgia of countless tourists for their hometown. In this era of rapid development of industrial production, many times, our pace is too fast to look back and wait for it. We only think of it when we occasionally touch it. There is also a kind of food that may not be beautiful, but it is a memory that can not be forgotten, which makes people warm and powerful in foreign countries.
