What was the social status of freed slaves after the American Civil War?

Although federal law recognizes the free status of black slaves.

However, there are no clear laws and regulations in the federal or state to ensure that people of color (including blacks) enjoy the same rights as whites, and even many laws and regulations restrict many important basic human rights of people of color, that is, they are in an unequal position with whites. People of color are still oppressed, discriminated against and even isolated. Until today, this situation has not been completely improved. Of course, compared with before the Civil War, people of color are no longer slaves. For a simple example, before the civil war, blacks were like captive golden monkeys, but after the civil war, they became wild golden monkeys. In modern times, they began to transition to real people in social, political and economic fields.
