As an entrepreneur and a National People’s Congress representative in the food industry, Zhang Lidian can be described as “wearing two hats.” On the one hand, he must provide suggestions for the development of the food industry, and on the other hand, he must fulfill his duties as a people's representative for the people. To this end, he will focus on the topics at the meeting that are related to the development of the industry and food safety issues that are closely related to thousands of households. superior.

In his proposal titled "Food companies must pass food laboratory certification before obtaining a license," Zhang Lidian pointed out: There have been many reports on food safety in recent years, and the country also attaches great importance to food safety. We attach great importance to it, but there are also some big problems that frequently arise. Food safety is related to thousands of households. If we want to control food safety, we must start from the source. Therefore, he believes that laboratories and central laboratories are very important. If every product can pass laboratory testing before being put on the market, then the product's qualification rate will definitely be very high. Moreover, consumers can be more assured by passing testing before leaving the factory. This time he made this suggestion mainly to strengthen one point through national legislation, that is: every food company must pass mandatory laboratory verification during the production process before obtaining a license.

Zhang Lidian said: At present, in Yashili Group, product quality is the lifeline of the company, and any market expansion and brand building actions of Yashili are rooted in this. When an enterprise is responsible for product quality, it is responsible for consumers and society. At the same time, the Yashili Group's business philosophy of "running a business in a down-to-earth manner and pursuing development in a down-to-earth manner" has become a deep-rooted corporate culture and is integrated into the blood of every Yashili person. Yashili Group has been enthusiastic about public welfare and helping those in need for many years, which is another manifestation of improving corporate responsibility.
