A woman coaches her daughter to practice acrobatics in Changchun City, Northeast China’s Jilin Province. Twin brothers Chen Kun and Chen Peng, now 40 years old, got to know twin sisters Gao Ning and Gao Ding, now 38 years old, when they learned acrobatics together. The identical twins paired off and each family has a daughter, who practices acrobatics with their parents. (Photo: China News Service/Zhang Yao)
