This is a bunch of working class Chinese immigrants who came to California looking for gold.
This is a family who came to American during the 1890s. They look different from the previous picture because they look like they were ready to settle in American and they don’t look like they going to dig for gold or anything. In the first picture of how people dressed, we can see that they still keep some of their Chinese dressing style as well as the second picture. The first picture also shows that 5 people staying in one big room, maybe they will be sharing this room for their stay in America, showing the hard living environment in America during the immigration period.
