I use the website: http://www.storycorps.org for primary sources in my high school history class. Storycorp is an NPR project to gather oral histories and create short videos or animations to share our stories with the world. I have found multiple stories to connect with lessons on East Asia. These are a great way to introduce a topic, add technology in the classroom through digital sources, or simply build empathy in the classroom. Here are a few videos that I've found:
