A study of Los Angeles Chinatown reveals that Chinese migrants in the late 1800s established a self-reliant economy by engaging in pig-raising and pork distribution. Despite discriminatory policies such as the Chinese Exclusion Act of 1882, researchers Jiajing Wang, an assistant professor of anthropology at Dartmouth College, historical archaeologist Laura Wai Ng and Tamara Serrao-Leiva, curator of anthropology at the San Bernardino County Museum, found that these migrants found a solution to counter discriminatory policies in creating their own economic system.
