Ni Zijun, who was almost 5 years old, finally met his mother at the radio registration office. It was only 24 minutes since he separated from his mother in the Expo Park.

At 16:02 on June 10, an armed police soldier standing guard at the European Square of the World Expo brought a boy crying for his mother to Qi Lingyi, a volunteer in the park from Shanghai University of Traditional Chinese Medicine. After patient inquiry, Xiao Qi learned that the boy from Nanning, Guangxi was Ni Zijun. He was less than 5 years old this year and had just separated from his mother and grandfather in the park.

Qi Lingyi comforted Xiao Zijun and led him to the nearest information office. When he learned that the mother who had not searched for her son had come, he led the child to the radio registration office in the Expo Park. The staff at the registration office asked Xiao Zijun if he remembered his mother's mobile phone number, but he only got a six digit fixed phone number - the child was still young and could not tell the details clearly.

When the staff tried to connect the boy's family in Nanning through this number, Ni Zijun's mother, Ms. Zeng Ying, walked into the registration room and saw her lost son.

It turned out that when Ms. Zeng found that the child was missing, she immediately found the police on duty in the park. Under the guidance of the police, she directly found the radio registration office in the Expo Park. Unexpectedly, she saw the child led by the volunteers just after arriving here.

It was only 24 minutes since Ms. Zeng and her child separated.
