This research aims to discuss the possible COVID-19 effect on China's real estate market from the perspectives of market demand, supply, government, agency and banks. This paper has explained the reason of recovery of the real-estate market with statistics and economic theories. The initial recession of the real estate market is due to the temporary closure of the offline office and prohibition of in-person visiting. This paper also quoted the figures to visualize the fluctuation of the market demand, supply and price. The subsequent recovery of the market was attributed to the expansionary government policy, business innovation of the online platform and consumer's return to work. The research work wants to provide a meaningful guideline, to the government, real-estate developers and relevant parties, about the evolutionary paths under the dramatic external shocks.
