On November 9, 1842, Lin Zexu came to Huiyuan from Xi'an after four months and lived in a quiet private house in Huiyuan for two years and one month. During this period, Lin Zexu ignored his old age and frailty and carried out large-scale water conservancy projects. He dug canals and diverted rivers to irrigate farmland. He personally undertook the Kashgar River water diversion project and irrigated one-third of the cultivated land in the Yili area, turning wasteland into fertile farmland. It still benefits local people, and this canal is called "Lin Gong Canal" by later generations. He also promoted "karez" and advocated inland spinning and weaving technology, which played an important role in Xinjiang's economic development.
