明末在内外交困的情势下,徐光启等开明之士主张从澳门募兵购炮以对抗后金之侵扰。崇祯三年,葡国统领公沙.的西劳率铳师队伍抵京,负责练兵教炮,颇有成效。为推进军事改革,徐光启派员再赴澳门募兵数百,但因卢兆龙等人的强烈反对而未果。崇祯四年,孔有德发动吴桥兵变,并率受葡国铳师训练之部队携西洋火炮降金,致使后金军事实力大幅提升,成为其攻城掠地、入主中原的关键之一。 At the end of the Ming and Qing Dynasties, both internally and externally, Xu Guangqi and other enlightened people advocated recruiting troops from Macao to fight the invasion of gold. In the three years since Chongzhen, the team of the West Laotian troops headed by the Portuguese state arrived in Beijing and was responsible for training the military canons. To promote military reform, Xu Guangqi dispatched hundreds of troops to go to Macao again, but he failed because of the strong opposition of Lu Zhaolong and others. In the four years of Chongzhen, Kong Youde launched the Wuqiao military coup and was led by troops trained by the Portuguese troops in the Western artillery to drop gold, resulting in a substantial increase in the military power of the Houjin and one of the keys to its invasion of the Central Plains.
