A few catties of pig's head are packed in plastic in a first-hand shop in Shenyang.

Plastic packaging generally takes 0.58 kg as the packaging standard.

The first-hand shop was established in 1995. After more than ten years of development, it has developed into a large-scale comprehensive food enterprise with five branches in Beijing, Shenyang, Harbin, Taiyuan and Xi 'an, and nearly 1,000 specialty stores and hotels. The first-hand shop is committed to the research, development, production and sales of non-staple food, adhering to the corporate purpose of "quality first, reputation first". At present, several series of products, mainly smoked products, bean products, canned products and fried products, have been formed, which greatly enriched consumers' dining tables and met their dietary nutrition needs. The first-hand store strictly controls and monitors all aspects of raw material supply, production technology, transportation and sales, and forms a complete and rigorous management system to ensure food quality and safety, and has successfully passed the QS ISO900 1 international quality management system certification and food quality and safety certification.
