A woman surnamed Yan bought a decorated apartment priced 12.3 million yuan early this year in Harbin, capital of northeast China's Heilongjiang Province. However, she found mushrooms growing in the wall of the sitting room recently.

Yan talked to the real estate developer many times. Finally a manager surnamed Gao said he will send workers to Yan's home to deal with the problem. During that period, Yan's family can stay in a nearby hotel and the developer will cover the expenses.
