本文以沈阳市为例从满汉文化比较中找出我国北方城市中存在的大量的藏匿的满族群体。笔者将从历史的角度分析其消失的根本原因——清王朝灭亡后满族旗人因成为社会革命对象而散佚、藏匿。同时,利用巴斯(Fredrik Barth)的关于族群及其边界以其文化为基础而形成的理论来说明这一部分已改变其民族身份的人们仍在城市中保留有其特有的文化圈层,从这一点来说,城市中大量藏匿的满族虽然身份上是汉族但实际上仍是满族。 This article takes Shenyang as an example to find a large number of Manchu groups hiding in the northern cities of our country from the comparison of Manchu culture. The author will analyze the root causes of its disappearance from the historical point of view - the Manchu bannermen of the Manchu people disappeared and hid because of becoming social revolution objects after the Qing Dynasty ’s demise. At the same time, taking advantage of Fredrik Barth’s theory of ethnic groups and their boundaries based on their culture, that this part of people who have changed their national identity still retains its own cultural circle in the city, In a word, the Manchu massively concealed in the city is actually a Manchu although it is Han nationally.
