From April 20 to April 22, the China Shanghai International Technology Fair was held at the Expo Exhibition Center. Exhibitors and inventors from all over the country and in the world gathered on the east bank of Pujiang to showcase their latest ideas and most creative products. Han Zheng, Secretary of the Shanghai Municipal Party Committee, and other delegations also visited “the Shanghai Youth Science and Technology Invention Exhibition” on the Shanghai Fair, and carefully watched the inventions of the small inventors.

This year's Shanghai International Technology Fair has such a group of middle school students. Their Chinese style school uniforms have become the most beautiful scenery on the Shanghai International Technology Fair. They are the "seat timeshare rental system" team and the "line array LED skipping rope" team from SHDFZ. After a one-year incubation of innovation and entrepreneurship projects, the 2 teams were awarded certificates of participation at the launching ceremony on the 20th, and demonstrated the innovation results of their teams in the Shanghai International Technology Fair.
