On June 18, the reporter learned from the Hainan Provincial Real Estate Association that the association has recently issued a notice in the form of a red-headed document within the member units, and will carry out the "Commercial Housing to Promote Consumption Action" across the province from the date of the notice. The reporter learned that this is also the first time since Hainan implemented the "Global Purchase Restriction" in April 2018 that a major "real estate to promote consumption" activity has been guided by government departments and led by industry associations. Activities include "group buying discounts". Real estate development enterprises provide group buying exclusive housing and exclusive discounts, and carry out group buying for government agencies and institutions, central enterprises and state-owned enterprises, Financial Institutions Groups, industrial parks, large private enterprises, relevant industry associations, chambers of commerce, etc. Commercial housing is traded in for new "national free commission". The period of "national free commission" is in principle not less than 3 months, and the specific period is determined by the real estate enterprise itself.
