In the 1950s, Mr. Yang Zhenfa, the founder of the Yang Ji Family signature sweet potato crisps, sold them by pushing a tricycle along the streets. Many older residents of Taitung still remember him. 'Uncle Zhenfa' was known for his honesty, integrity, and diligence. Currently, the business is meticulously managed by the second generation, the founder's youngest son and his wife (Yang Junming and Zhang Yuehong), who adhere to traditional methods to produce unique sweet potato products. A tricycle left by my father, sweet potatoes that have supported us for forty years, and the most traditional ancient sweet potato flavor still passed down in our generation.
