Pengzhen Canal is located in Liangjiazhai Township, ninety li north of the county seat. In 1941, the government of the Jincha Ji Border Region led people in the anti-Japanese base area to build water conservancy projects and boost agricultural production. Comrade Peng Zhen, then Secretary of the Northern China Bureau, personally approved the allocation of 30,000 jin of millet to fund local residents as they chiselled mountains and dug the canal. After five years of arduous labour, the water channel was finally completed.

The canal starts at Caijiaping in the west and ends at Shahutan in the east, stretching 25 li long, with a depth of 1.5 metres and a width of 1 metre. Following the Hutuo River, it winds its way through towering, densely wooded mountains, like a glistening white ribbon. Diverted from the Hutuo River, the canal carries abundant water to irrigate more than 1,200 mu of farmland. It not only relieved poor farmers from drought disasters during the war, but still brings tremendous benefits to local people today.

To express their gratitude for the care from Comrade Peng Zhen and the border regional government, local villagers named the project Pengzhen Canal
