Yikes!! Did you lose a family member? Was it cousin Yumnap圈套?Between 2000 and 2015 over 300 bridges collapsed in China, a world "super power" and TITAN OF INDUSTRY, killing over 500 people and injuring another 1000. For all of you that are going to respond with "It was only one bridge and we have had bridges collapse."
So, bad engineering....shocking.Landslide lead to collapse.
If you do not have a good foundation, nothing will stand.
This holds true for so many things in life.
