As far as district finance is concerned, Dong 'an District is the richest, and the relative construction is better, followed by Xi 'an District, but the west is mostly inhabited by Koreans, and Aimin District is the poorest among all administrative districts in Mudanjiang.

Pure mobile phone, hope to adopt.
