In February 2017, I learned about Kids World Exchange, an organization founded to enable kids from China and the US to speak with one another through recorded videos. The idea came about, I think, because of the time differences between the two countries and the difficulty in finding a video buddy with similar interests.
You can see some of Kids World Exchanges videos on their YouTube Channel.
They had a nation-wide contest where they asked kids to share their favorite local places and to speak about it in Mandarin. Below was my entry, which won first place!
