What is the law of Shandong Reservoir's migration to Heilongjiang in 1950s?

There are no rules. In the 1950s, due to the development of the country, it was said that the residents of Shandong reservoir area migrated to other provinces such as Heilongjiang, and there were no regulations in the process of migration, as long as the residents were settled down, which also ensured the smooth implementation of the reservoir resettlement support policy and safeguarded the legitimate rights and interests of immigrants. Heilongjiang Province, referred to as "Hei" for short, is a provincial administrative region of China people.
