You'd be surprised to see how chaotic & booming the construction market is in China. Everyone is making money in one-off fashion like no tomorrow, and yet somehow even the most stupid contractor survived while keep making rookie mistakes after all those years. There are quality builders in China, but construction industry as a whole had zero to none barrier of entry, thus it had the highest concentration of dumbness in 1.4b ppl. China was undergoing the most dramatic urbanization period of human history, the demand is huge. So yeah it's an economical issue.
