As the first event of the Youth Education, Mr. Chang , the keynote speaker of the Rotary Elementary School, and Mr. Feng, the keynote speaker of the Hebei Central Primary School, vividly explained basic knowledge such as the light, light speed, and the straight line of light.

The children all happily listened to the teacher's lectures. When talking about the small hole imaging, Mr. Chang also gave a demonstration experiment for the students, so that the students knew that the characteristics of the small hole imaging.
