A four-year-old boy burst into tears as he could not find his classroom at kindergarten after the three-month coronavirus quarantine in central China.

The funny and cute video, shot in the city of Xuchang in Henan Province on May 11, shows a boy crying while saying to his teacher, "I cannot find my classroom," on his first day back to school.

His teacher named Ma then asked him: "Who is your teacher?"

The boy said: "I don't know either."

Miss Ma: "Can you look at me? Do I look like your teacher Miss Ma?"

The boy continuously cried: "I cannot recognise."

"Let's go into the classroom. I am your teacher Miss Ma," Miss Ma said.

In another clip, filmed in the next day, the boy finally remembered his teacher and smiled.

The video was filmed and provided by Miss Ma with permission.
