From November 16th to 18th, the practical teaching of "China Studies: Industry, Society and Culture" of the Department of Industrial Engineering of Tsinghua University came to Linyi. With the development of industrial cities brought about by new quality productivity as the research target, more than 30 international students from Germany, Russia, Thailand and other countries visited Shandong Lingong Engineering Machinery Co., Ltd., Shandong Chunguang Technology Group Co., Ltd., Wanhua Hexiang Ecological Technology Co., Ltd. and other companies, and entered the front line of Linyi's industry to cultivate new quality productivity, and felt the unique charm of Linyi's industrial development up close.

When visiting the production workshop, the international students were deeply attracted by the advanced production equipment and efficient production process of Chunguang Technology Group. They all said that this visit gave them a more intuitive and profound understanding of the industrial development of Linyi City. Xi Wang, an international student from Portugal who studies mechanical engineering at Tsinghua University, exclaimed: "It is really great to see the scale of Linyi's industrial development. Every company I visited this time has a strong industrial capacity, a high degree of automation and a lot of technological content, which shocked me."

Through this practical activity, the international students not only gained more knowledge and broadened their horizons, but also deepened their understanding of China's industrial development. They all said that they would bring back what they saw and heard in Linyi City and share it with more friends, so as to contribute their own strength to promoting industrial exchanges and cooperation between China and foreign countries.
