Recently, an IT software engineer with the surname He from Shandong, told his “heartbreaking” home buying experience on the internet. He spent nearly $1.5 million (10 million yuan) to buy a beautifully decorated house in Shanghai and discovered 52 construction errors during the construction. Because he moved to his new house to monitor the progress of building, he was plagued by various diseases due to the excessive amount of formaldehyde used. His health has not improved even after four years of treatment.
