To save 3,000 yuan, 25-year-old Zhang Yuan canceled the third-party home inspection service for his future marital home. His reasoning seemed perfectly sound: there were only 30 inspection checkpoints, and all the inspector did was take a few photos and tap the walls with a little hammer. It seemed far too easy to earn that money. But the consequences came faster than he expected. On the day of the plumbing and electrical inspection, a water pipe joint suddenly burst, spraying muddy water all over his father-in-law. Three workers stood in ankle-deep water, blaming one another, with nobody willing to take responsibility. What made things even more embarrassing was that his father-in-law had worked in construction for 30 years. He entered the site with a measuring tape and, without saying a word, measured a junction box that was five centimeters off. Only then did Zhang Yuan realize that it wasn't that nobody was supervising the work—it was that someone actually knew how to spot the problems.
