《明史·列传·卷六十》
白圭就建议大举搜索河套，调发京军及其它镇兵十万屯居在延绥，而以运输军粮督促河南、山西、陕西人民，不能供应，就提前征收第二年的赋税，于是内地动荡。
圭乃议大举搜河套，发京兵及他镇兵十万屯延绥。而以输饷责河南、山西、陕西民，不给，则预征明年赋。于是内地骚然。
Then Bai Gui suggested a large-scale manhunt on the Hetao Plain. He mobilized 100,000 soldiers from the capital as well as other garrisons to garrison Yan Sui and urged the people of Henan, Shanxi and Shaanxi to provide provisions for the army. If they failed to do so, they would have to pay double the taxes the following year. This caused unrest within the country.
