Training children's logical thinking and creativity, the Chinese Ingenious Wisdom Development Association promotes Chao Zhi Wisdomball. Last year, the first competition was held, and among the five participants from Dazhi Elementary School, three ranked in the national top eight. This impressive achievement led the organizers to designate the school as a promotion center and establish the Chao Zhi Classroom. On this day, a trial class was held, and the students had a great time enjoying the activities.
