The country has resolved more than 20 million units of historical legacy housing issues, allowing people to not worry about "red books" anymore.

The Ministry of Natural Resources recently stated that since the implementation of the unified real estate registration system in 2015, more than 20 million historical problem houses have been resolved nationwide, and various prominent issues related to certification have been effectively resolved. Especially since 2024, more than 3.4 million long-standing "tough problems" across departments have been resolved nationwide. For a long time, some residential projects have had missing registration documents due to inadequate coordination in the front-end process and inadequate supervision, making it difficult to register and obtain certification. This has caused many homebuyers to hold keys but not be able to get the "red book", making it difficult for their assets to circulate, and difficult for school enrollment and household registration. It has become a big burden for them.
