## History

During the rule of the Ming dynasty in China, Yilan, formerly known as Sanxing (三姓; Wade–Giles: San-hsing; historically also Romanized as San Sing), was one of the two important centers of the Jianzhou Jurchens of the Hurka River valley. (The other center was Ninguta in the upper reaches of the Hurka). Its Jurchen name was Ilantumen.
The town retained its importance into the Qing period, and in 1692 became the seat of a deputy lieutenant-general (副都統; fù dūtǒng). Subordinated to the governor general (jiangjun) in Jilin City. the Sanxing fu dutong was in control of the northeastern section of Jilin Province (which in those days was much larger than now) – a large region stretching northeast along the Sungari and the Amur to the Pacific Ocean.
In 1887, three British travelers – H. E. M. James, Francis Younghusband and Harry English Fulford – visited Sanxing on their tour of Manchuria. According to Fulford's account, the town had the population of around 10,000, trade in furs and fish (salmon and sturgeon) being its main industries.
Lu Houmin, who was the official photographer for the top Chinese leaders particularly Mao Zedong from 1950 to 1964 was born in Yilan.
