What is the relationship between the Human Resources and Social Security Bureau and the Labor and Employment Bureau?

Just from the literal understanding of the words, human resources and social security bureau covers a wider range, because it is not only labor and employment, there are other functions including social security, such as social security, health insurance. Because they all belong to the government agencies, some places have different subordination, if they are all bureau-level units belong to the same level, some places on what what section, the national level is the People's Republic of China **** and the State Ministry of Human Resources and Social Security and the Department of Labor Relations.

I hope to help you, please adopt the points, thank you.
