5-Beef
In general, buying any kind of meat from China is not a good idea. Due to the production process, much of the meat is riddled with diseases that can make you seriously ill.
Chinese meat shops are known for their fast production and not exactly ideal safety standards, so much of the meat comes into contact with unwanted bacteria. In addition, Chinese meat shops tend to mix several things together to create something that looks and tastes like beef, but is not real beef. If you buy beef from China, you could actually use a mixture of chemicals, paraffin wax and who knows what else.
