At church I heard that the untold story here is that Hong Kong has a very large Christian presence and they evangelize atheist China.
There is definitely an interest in the Bible and Bible Prophecy in Hong Kong.
Long ago there was a Christian guy (Chinese) who was trying to evangelize Hong Kong. I do hope the Lord blessed his efforts and him too. I’m sure He did.
