In 2019, the sophomores of 10 Wenxin high schools will ride 3000 kilometers to participate in 2050, bringing the teachers and students of the whole school. By this year, the cycling students at that time had already entered the University. This year, eight new students started cycling. In the past two years, 2050 volunteers have been reunited several times in Wenxin high school, and Wenxin teenagers have also seen the rocket launch. This time, these old and new students and volunteers will come back to reunite again.
