I have never been impressed with the moral quality of my fellow countrymen. So I chose as early as possible not to have business dealings with them. The occurrence of the Sanlu milk powder case once again confirms that my choice was right. Immorality, this is not just a problem of a certain person, but a problem of the entire national character. There is something wrong with human nature! From top to bottom, from bottom to top, it has been like this for thousands of years. To change? Hard! Too hard! That's why there are so many black-hearted manufacturers who不顾people's lives and openly add melamine to milk powder.
