My wife (ethnic Chinese from Thailand) and I lived in Sichuan, PRC for three years from 2007 to 2010. There were many Chinese Christians we met during those three years and also during our trips to China that began in 1998. The Chinese Christians are serious Christians (persecution does that to a person) and will never be defeated by government hacks. There are too many and too diverse with about 80% worshipping in illegal house churches. Believe the number of active Christians (and I mean ACTIVE) is close to 300 million per our Christian friends.
The Chinese art you showed reminded my of a Christian traditional watercolor artist that taught my wife his art form. His Christian silk scrolls were exactly as you have depicted. Wonderful and very traditional Chinese. Thanks for sharing.
