Yu Yonghe (traditional Chinese: 郁 永河) was a traveler from China whose adventures are recorded in The Small Sea Travel Records (traditional Chinese: 裨海紀遊). The book contributes significantly to the research on the historical development of Taiwan in the seventeenth century.
Yu Yonghe was born before 1650 in the city of Renhe, Zhejiang province. Modern scholars have regarded Yu as one unique figure of his time because of several factors. For instance, although traveling was not uncommon at his time, Yu was known to have travelled to every corner of Fujian and even to Taiwan – a desolate and barbaric island back in the seventeenth century. Furthermore, shown both in his account of the Aborigines (番境補遺) and Zheng family (偽鄭逸事), his knowledge of the foreigners and interest in foreign lands were extraordinary for his era. Notwithstanding Yu’s relatively wide exposure to foreign lands, he was blunder in regards to his account of the 「red haired barbarians」 as well as other Western countries.
Under the consent of the Fujian officials, Yu travelled to Taiwan following the explosion of the Fuzhou gunpowder stores in 1696 to mine sulfur. Yu’s voyage began at the coast to Xiamen, crossing the Taiwan Strait and coming to a halt in Penghu before arriving in Tainan. Yu then journeyed northward to Tamsui and Peitou where he bought amorphous sulfur from local Aborigines for the making of pure sulfur. The expedition lasted for ten months. Eventually Yu returned to Fuzhou with a memoir of his ten-months journey aboard. The memoir chronicles Yu’s life in Taiwan when he was introduced to the unique culture of the island. It subsequently became The Small Sea Travel Records. As Yu was on the mission of collecting sulfur, his book is also referred to as the "Sulfur Extraction Diaries." The book provides first hand account of the most vivid historical records of the period.
When Yu arrived in Taiwan, the island had been under the administration of the Ching dynasty for 13 years. Not only had Yu recorded the developments of the era, he had also taken into account of the administrative structures passed down by the Dutch and Zheng dynasty.
Unlike other primary records left by conquerors and administrators in the seventeenth century, Yu’s book reflects the multicultural characteristics of early Taiwan through the eyes of a adventurous and passionate literati.
