hina Property: a quick animation (link found below) showing how Guangzhou, Chongqing and Yangzhou are the top cities in terms of the cumulative house price growth (NBS new home sales price indices for 70 major cities) so far in 2021 (Jan-Jun).
One data caveat is the administrative project-level price caps on new homes sales in a number of cities, typical when the policy is in the tightening cycle. Also, the NBS price metric tends to capture the more core city areas, less so the county-level cities.
