Fourth baby dies from tainted milk formula

In China, there are 4 babies that got kidney stone. I know that you will curious about why? and how? It is because there is a company that sells tainted milk formula in China, and the tainted milk formula has already sickened more than 6200 babies. They arrested 12 suspects early today in China, but they are still not sure whether they are the right people. This is really dangerous for babies, because if they drink those milk formula, then they are easy to get kidney stone. Kidney stone is a disease which can kill people easily, and babies are weak, so we hope that all those babies will be alright. This tainted milk formula shows that China is a country where people don't really care about each other, no defense to them, it's just we hope that these kind of stuff won't happen again, because it's bad for everyone.
