Willow Palisade (Chinese: 柳條邊; pinyin: Liǔtiáo Biān; Manchu: ᠪᡳᡵᡝᡤᡝᠨ
ᠵᠠᠰᡝ; Möllendorff: Biregen Jase) was a system of ditches and embankments planted with willows intended to restrict movement into Manchuria, built by the Qing dynasty during the later 17th century. It is often conveniently divided into three connected sections: the western and eastern sections, forming the Inner Willow Palisade around Liaodong Peninsula, and the northern section, also known as the Outer Willow Palisade, separating the traditionally Manchu areas (to the east) from the traditionally Mongol area (to the west) north of the Inner Palisade.
Manchuria borders Mongolia in the west, Siberia in the north, China proper to the south and North Korea in the southeast. Inner Manchuria has access to the Yellow Sea and the Bohai Sea to the south, while Outer Manchuria has access to the Sea of Japan and the Sea of Okhotsk to the east and northeast.
To the south, Jilin was separated from China proper by the Inner Willow Palisade, which restricted the movement of the Han civilians into Jilin and Heilongjiang during the Qing dynasty, as the area was off-limits to the Han civilians until the Qing started colonizing the area with them later on in the dynasty's rule. Only Bannermen, including Chinese Bannermen, were allowed to settle in the area beyond the Willow Palisade. This palisade, often conventionally divided into the eastern and western sections, started in the hills near the Great Wall of China (inland from Shanhaiguan) and ran northeast toward a point located some 33 km north of Kaiyuan, Liaoning, where the Outer Palisade (see below) joined the Inner Palisade. From this junction point the eastern section of the Inner Palisade went eastward, toward Korean border, and eventually southward, ending near the mouth of the Yalu River.
