Six of one; half-a-dozen of the other.
I've lived in Hong Kong and Taiwan for 12 years before I moved to Thailand and have traveled extensively through China for more than 25 years. As such, I've probably read more about China than you've been able to find in Wikipedia or been told by some crazy blind woman.
Here try this one on for size.... the first legitimate article I found by googling. Note that it's from eight years ago. You can find hundreds of similar discussions of the count with all sorts of estimations. None agree with the official count of the government.

And yet still more Christians than the entire population of the Philippines. And soon to probably surpass the Christian populations of all other countries, the way it's been growing.
You cite percentages when they're convenient and raw numbers when they'll suffice. The point we've been making is that your ridiculous romantic notion of a couple of persecuted individuals holding services in the Chinese version of The Catacombs is absurd. Fifty or seventy or ninety or one hundred thirty million is a huge number. And regardless of the number cited by various "experts", the one thing they all agree upon is that the Christian population is growing exponentially.
You found that on some website, right? It's word salad. You know nothing about China or the Chinese.
