A video of a boy from Southwest China's Yunnan Province carrying a mop for a nucleic acid test on Friday went viral on Chinese social media. The teacher explained that the school has carried out nucleic acid tests five times already, and the boy threw up each time while being tested.

This time, he decided to bring a mop in advance.

According to the teacher at the school, the last time the child vomited at the scene, the principal started anxiously looking for a mop, so just in case, to relieve the teachers of this responsibility, the child brought his own mop, painting a picture both sad and funny.

As of Sunday, there were 14 confirmed cases and 6 asymptomatic infections in Yunnan.

"The child has a great sense of responsibility and is also very brave, but I can't help thinking this looks hilarious," one netizen commented.
