From Investing in Chinese Stocks:
On September 19, Hangzhou announced buying restrictions:
The city authorities said that, effective from Sept 19, homebuyers without household registration in the city-known in Chinese as hukou-are not allowed to buy a second home in the city’s central districts, in a bid to curb rapidly rising house prices, curb speculative buying and prevent risks.These restrictions were tightened again on September 26, with total ban on non-resident buying, touching off a housing frenzy in Hangzhou.
