California schools to teach Chinese Exclusion Act and history

The 1849 Gold Rush in California ignited dreams of newfound fortune, attracting would-be miners from around the world including China. The search for gold as well as the dramatic increase in demand for laborers triggered a surge in Chinese immigrants to California as the biggest project of that era, the Transcontinental Railroad, which connected the western and eastern halves of the US. In the total of 20 years, it's estimated a total of 108,000 Chinese. Now, the whole history is being brought to students in California. CCTV America's May Lee reports the story.
