There are Christians in China; missionary work proceeds.
You are correct. Yes, it does. The biggest portion of them come out of Hong Kong. It's a much older point of Christianity.
1. Getting past the Chinese culture is the tough part. Christianity requires a certain submission to forces other than luck and money. Those two things are SUCH a huge part of Chinese society.
2. The other part of China that will take just as long to change is their abysmal attitude toward women. Female babies were LONG discarded, left on the street...and worse.
Males are worshiped; females are too often aborted as fetuses. The Commies have had a TOUGH time getting couples to NOT abort the ONE girl, the ONE child they are allowed to have.
At one time there were so many female fetuses aborted (thanks to amniocenteses) that an entire generation of males had no women to marry. Those unmarried men were called the Bare Branches.
China will make sure THAT doesn't happen again.
China has been around a l-o-n-g time, like India, and both countries have a superiority complex. It DOESN'T matter than neither country has a pot to piss in, they revel in their ancient heritage. SO, getting the Chinese to change their male-adoration attitude isn't going to happen any time soon.
Work proceeds, as you say. They are going to need a MASSIVE kick-in-the-butt about females, via Mary, from the Holy Spirit. HE can do it
