In order to further carry forward the May 4th spirit of "patriotism, progress, democracy and science", activate the company's working atmosphere, stimulate employees' morale and vitality, and enhance positive energy. On April 26, when the May 4th Youth Day was coming, the company organized all employees to watch the historical feature film My 1919 in the conference room. In the process of watching the film, anger and tears coexisted. At the end of the film, everyone was still reluctant to leave.

My 1919 is a unique film. It shows a long history, that is, at the "Paris Peace Conference" in 1919, the Chinese representatives refused to sign the "peace treaty" that humiliated the country. This is the first cry of China in the face of Western powers in the modern international diplomatic situation. Although this voice is indeed weak and thin, it is the first time that Chinese diplomats have stood up for the backbone in the 80 years from 1840 to 1919. When recalling the May 4th Movement, we should not only remember Beijing and Shanghai, but also remember Paris, Gu Weijun and others' struggle and efforts, courage and conscience.

After watching the film, everyone said they had benefited a lot. The film tells the historical background of the outbreak of the May 4th Movement, which makes people deeply feel the hardships of the Chinese nation in pursuing dreams for a hundred years. They also said that they would be down-to-earth in their future work and life, constantly improve themselves, forge ahead, be brave in innovation, and contribute their own strength to the development of China's environmental monitoring industry.
