I'm so sleep deprived due to an adorable puppy who has no love for his crate (mind you, he does seem to be getting more used to it; last night he stayed in it for several hours without much complaint) that I read this as "Chinese dog breeder sells Taliban mastiff twins to property developer for $3 million."
My little pup weighs around 13 lbs. I wouldn't care to speculate about the combined weight of the year-old mastiffs.
The new owner had better have two gigantic crates--and fingers crossed that the massive ones aren't averse to them.
Going by photos of the hyper-hirsute breed, I'd say he's going to need a really good vacuum cleaner, too.
