It says in that Chinese website ( translated to English ): Four companies have more than 100 billion yuan in interest-bearing liabilities due within one year. Evergrande, Sunac, Greenland, and Country Garden amount to 395.7 billion ( $56 Billion), 140.6 billion ($20 billion ), 121.4 billion ($17 Billion) , and 105.8 billion ($15 Billion ), respectively. There are 6 companies with interest-bearing liabilities exceeding 50 billion-100 billion yuan due within one year, namely Vanke, China, R&F, Tahoe, China Merchants, and Poly.
Yes, these are large sums, but not impossible for the government of China to bail out ( just like the Feds did with our banks and mortgage companies during the 2008 financial crisis ).
