Christianity in China

Here's an interesting article: "Recent surveys calculate the number of Christians worshipping independently of the State churches in China to be as high as 100 million. That means that almost one in every ten Chinese may now be a Christian, making Christianity bigger than the 74 million-member Communist Party." I live in a pretty international town and attend a pretty international church with a lot of Chinese folks. I've asked them about this in the past, and they told me that Christianity is fashionable in China right now, meaning that it's popular but some of it is superficial. But I've also heard estimates that east Asia, and China in particular, will be the global center of Christianity within the next 30 years.
