Chinese Underground Church - from the Movie "China Cry"
Christianity was banned in Communist China for decades, but there were Christians in China who kept their faith and shared it with others. In this "China Cry" which is based on Nora Lam's personal experience in China, you can see a group of Christians meeting secretly to worship God. They can't sing hymns loudly so they sing it without sound.
