On June 3, 2023, in the "Grand Vital Capacity Challenge" public welfare competition, the participants kept blowing up the floating ball and kept it up. Each participant could exchange for 5 yuan for every 1 second of persistence. Finally, through the joint efforts of the Granders, this challenge harvested a total of 4625 yuan of public welfare fund. GRG purchased a set of large-scale activity speakers for the central primary school of Shubao Township, Huili County, Sichuan Liangshan Prefecture in the name of each employee, for the daily collective activities of the school.
