How ridiculous this retroactive compensation mechanism is! It's like, a few months ago you bought a 50 million yuan flat in Shanghai, and now the market price has risen to 100 million yuan, and the developer is asking you to pay an additional 50 million yuan difference. Such an absurd thing, the most unbelievable part is that the seven giants in the U.S. have already signed it 😂 I can't even imagine how they could really sign it with two antennas in my head 😂
