They welcomed the citizens and students who participated in this ceremony. Later, they introduced Tianjin's vigorous efforts to promote the work of comprehensive science popularization. The significant elements of this Science and Technology Week were also given notice as efforts to further popularize scientific knowledge.

Subsequently, Professor Liu Xinqi from the College of Life Sciences of Nankai University delivered a science report. During the lecture, Starting the Body's Hard-Core and Targeted Strike- a Brief Introduction of Vaccines and Ingenious Life, he explained helpful knowledge in a simplified way, including the immune mechanism, different types, and inoculation purposes of the COVID-19 vaccines. 

On the day of the opening ceremony, the life science group activities were held in the Comprehensive Laboratory Building. With the help of Nankai teachers and students, citizens in the laboratory have carried out a series of scientific experiments, both interesting and relevant to daily life. These activities included microbial graffiti, DNA extraction from strawberries, microscopic observation of plant cells, butterfly specimen production, and flower structure analysis. Meanwhile, they also attended the popular science lecture Knowledge and Observation of Drosophila. They visited the College of Life Sciences laboratories and learned more about its research equipment. Through those unusual activities, participants learned more about the daily life of scientific researchers and were able to seize the joy and significance of scientific investigation.
